In the pharmaceutical and biotech industries, one size often does not fit all when it comes to chemicals and reagents. Enter custom chemical solutions – bespoke formulations and syntheses made on-demand to meet specific R&D and production needs. This article explores how on-demand chemical formulation is rising, why pharma/biotech companies are embracing it, and what benefits and considerations come with this tailored approach.

Why “One-Size-Fits-All” Chemicals Fall Short

Modern drug development and biotech research push into new frontiers, often requiring unique reagents that aren’t available off the shelf. Standard catalog chemicals might lack the precise specifications needed for a cutting-edge process or a novel therapy. For example, a biotech startup developing a cell therapy might need a growth media with an unconventional combination of nutrients – something not sold premixed by any supplier. Historically, researchers had to MacGyver solutions by mixing standard products or compromising on formulation. But with today’s accelerated innovation, waiting for the “closest available” chemical can slow down R&D. This has fueled demand for on-demand formulations that are “tailor-made” to exact requirements.

Moreover, some “hard” chemistry problems – like synthesizing a rare reference compound or an impurity standard – can’t be solved by shopping a catalog. Custom chemical synthesis services have emerged as game-changers, allowing pharma companies to obtain novel compounds that are nowhere commercially available or are patent-protected. In short, the complexity and specificity of pharma/biotech pipelines have outgrown the one-size-fits-all supply model.

The Rise of On-Demand Formulations

Today, large suppliers and specialized firms alike offer custom and on-demand chemical services. Companies such as Thermo Fisher Scientific advertise extensive custom chemical capabilities – from tailor-made buffer solutions to custom synthesis of complex molecules – delivered as needed. The concept is simple: rather than you adjusting your process to available chemicals, the chemical is adjusted to fit your process. This includes:
– Custom blends and formulations: e.g. a buffer at an exact molarity/pH, a solvent mixture in a unique ratio, a cell culture media with proprietary additives.
– Custom synthesis: making an entirely new molecule or intermediate exclusively for the client’s R&D.
– Custom packaging and formats: providing a chemical in a specific package type or concentration (sterile, pre-dosed vials, etc.) to integrate smoothly into the production line.

The availability of these services has grown tremendously in recent years. Contract Development and Manufacturing Organizations (CDMOs) and specialized CROs have scaled up to meet the demand. The global custom synthesis and manufacturing market reached an estimated $271 billion in 2022 and is projected to hit $475 billion by 2028, reflecting how ubiquitous outsourcing of custom chemicals has become. Even small biotechs can now partner with experts to get chemicals “made to order” rather than investing in their own pilot plants.

Driving Factors in Pharma and Biotech

Several trends are driving the rise of on-demand chemical solutions in these sectors:

• Innovative Therapies Require Novel Chemicals: Pharmaceutical R&D is exploring complex modalities (gene therapies, antibody-drug conjugates, etc.) which often involve novel chemical linkers, unique reagents, or high-purity ingredients not available off-the-shelf. Custom synthesis enables access to novel and diverse chemical structures that would otherwise be out of reach.
• Speed to Clinic: Time is critical in drug development. Waiting months for a supplier to stock a needed chemical or spending time on internal synthesis can delay projects. On-demand formulation accelerates timelines – a needed buffer or intermediate can be created quickly by a service provider, ensuring R&D keeps moving. As one industry analysis noted, having compounds custom-made ensures a “consistent and uninterrupted supply” and mitigates delays due to commercial shortages. Researchers can focus on science while the custom provider handles the chemistry.
• Precision and Personalization: The push for personalized medicine and highly specific biologics means that processes (and their chemical inputs) are becoming highly tailored. For instance, a formulation for an mRNA vaccine might have very specific lipid nanoparticle composition. Custom formulation services allow fine-tuning of properties – concentration, excipient ratios, particle size, etc. – to hit the exact performance needed. Biotech companies can request “tweaks” to standard formulations (like media or buffers) and have them delivered consistently batch after batch.
• IP and Confidentiality: By synthesizing compounds in-house or via a trusted custom partner, pharma companies can protect intellectual property. They don’t have to disclose structures in procurement databases or wait for a patent to expire. Custom synthesis often comes with confidentiality agreements, so a pharma can pursue a novel compound without tipping off competitors.
• Scalability to Production: On-demand isn’t just for lab scale. Many providers support the full journey “from bench to production.” You might prototype a custom formulation in small batches, then scale it to manufacturing quantities seamlessly with the same partner. This continuity ensures that when a drug candidate moves to clinical or commercial manufacturing, the custom chemical inputs can scale too. For example, Thermo Fisher’s bulk custom services span grams to thousands of liters to support scale-up.

Benefits and Advantages

Embracing custom chemical solutions offers multiple benefits:

• Innovation Unlocked: Scientists gain access to compounds that don’t exist in catalogs, opening new research avenues. If they can dream it, a custom chemist can (often) make it. This leads to exploring novel therapeutic targets with unique molecules, potentially leading to breakthroughs.
• Improved Supply Chain Control: Instead of relying on scarce commercial sources, companies can secure their own supply by having chemicals made on demand. This reduces vulnerability to supply shortages or single suppliers. It’s essentially an insurance policy – if a needed chemical is hard to find, you have a direct way to obtain it. During COVID-19, for instance, many turned to custom manufacturing when standard supply chains failed.
• Faster Problem Solving: Custom formulation can solve downstream problems. If a formulation is unstable or an off-the-shelf reagent causes impurities, a custom variant can be formulated to fix the issue (e.g. removing a contaminant, adding a stabilizer). This accelerates troubleshooting and optimization in process development.
• Operational Efficiency: Outsourcing custom chemicals means you don’t need to maintain internal capabilities for every chemistry under the sun. This is cost-effective. A small biotech doesn’t need a full organic synthesis lab for one compound – they can outsource to a specialist. Similarly, purchasing a ready-to-use custom buffer saves time and labor on mixing and QC inhouse. As Thermo Fisher advertises, it can “save time and get exceptional consistency by letting us prepare your custom blends in our facilities.”.
• Regulatory Support: Established custom manufacturers provide documentation and quality
  that meet pharma standards (cGMP, etc.). They handle regulatory filings for novel substances or provide analytical data needed for your filings. This can simplify compliance since the custom partner often has experience with FDA/EU expectations for materials.

Considerations and Challenges

While attractive, custom solutions come with considerations:

• Cost: Custom synthesis or formulation services are typically more expensive per unit than commodity chemicals. You’re paying for specialized expertise and small-scale production. However, this must be weighed against the value delivered (time saved, unique capability). Many firms find the ROI is justified, especially when it speeds a drug to clinic.
• Lead Time: Creating something from scratch can take time (weeks to months) depending on complexity. Good planning is needed so that custom chemicals are ordered well ahead of when needed. Some providers mitigate this with faster service or by keeping inventory once you’ve ordered a custom product once.
• IP and Quality Agreements: When working with third parties, strong agreements are needed to protect intellectual property and ensure quality. Companies should audit and qualify custom manufacturers just as they would any critical material supplier.
• Integration: There can be an internal mindset shift. Scientists and procurement teams need to become aware of these custom options and use them strategically. Instead of saying “we can’t find X, project stalled,” the new approach is “let’s have X made for us.” Organizations that integrate this flexibility can move faster.

The trend is clear: on-demand, custom chemical solutions are rising as a key enabler for pharma and biotech innovation. They provide the exact tool a researcher needs, exactly when they need it, at the right specs. As a result, we’re seeing faster development cycles and the ability to pursue more ambitious molecular designs. In the quest for the next big therapy, having a “molecular concierge” – a custom chemical partner – is increasingly invaluable.
