A solution provider for innovator-focused HPAPIS

Highly potent active pharmaceutical ingredients (HPAPIs) are an example of compounds that can require a range of classical and advanced technologies to support their synthesis.

Typically, HPAPI projects can have several process steps, with at least some of these steps requiring reaction types such as amide coupling, chiral resolution, catalysis, biocatalysis, or cryogenic chemistry. HPAPIs represent an increasingly significant share of the pharmaceutical drug pipeline – especially for anti-cancer treatments.

Evonik has the largest capacity for custom contract manufacturing HPAPIs with more than 30 years of expertise in this specialized area. Manufacturing highly potent APIs safely in large volumes requires extensive project experience with toxicology, industrial toxicology, environmental health & safety (ESHS),  ergonomics and engineering. We are one of a few CDMOs which have the capabilities and experience to turn small-scale development lab quantities to large-scale commercial volumes with batch sizes of over 450 kg, with experience that dates back to the early 1990s. When you are considering the production of large volumes of an HPAPI, please come and see us to learn more.


In the past 20 years, the structures of APIs have become increasingly complex as the demand for specialized or personalized therapeutics increases, and innovators search for new chemical modalities in drug discovery and design. The average number of steps required for the chemical synthesis of small molecule APIs has almost doubled in the last two decades.

Using classical chemistries to synthesize APIs of increasing complexity is often not feasible or desirable. Most small molecules in clinical development require multiple different advanced technologies for a single synthetic sequence. Examples of advanced technologies used to synthesize complex APIs include containment for high potency APIs, continuous processing, synthesis and conjugation with PEGs and mPEGs, carbohydrate chemistry, online monitoring by process analytical technologies (PAT), catalysis and catalyst recycling, biocatalysis, cryogenic chemistry, as well as chromatography

It is challenging for any single pharmaceutical company or CDMO to develop a portfolio of advanced technologies that can accommodate the needs of all process steps involved in the production of such complex APIs.

For APIs requiring very special technologies – complex API chemistry – Evonik has a broad portfolio of advanced technologies. Whether you require complex synthesis of more than eight steps or certain building blocks such as chirality, you can partner with us for expertise and reliability.
