Your leading global contract manufacturing and development organization for APIs and HPAPIs


Contract manufacturing organizations (CMOs) and contract development and manufacturing organizations (CDMO) provide companies with the peace-of-mind they need to work on challenging drug development and drug manufacturing projects. By partnering with a CDMO you benefit from comprehensive services. Evonik is one of the world’s largest contract development and manufacturing organizations (CDMO). We have unique core competencies across chemistry, engineering and biotechnology and combine these with a proud record of performance for quality, supply security and sustainability. With a business-for-business (B4B) philosophy, we embrace the shared interests of all businesses – no matter the size – because we know that everyone benefits from a stronger and more purposeful collective effort. 


Over more than two decades we have worked with customers on innovator-focused HPAPI projects and complex API processes. Our established manufacturing network supplies APIs, HPAPIs and intermediates from clinical trial demands up to the largest commercial volumes. If you are looking for a reliable partner with high-quality production and a sustainable supply, we can help you – regardless of your project size or complexity.

When you partner with Evonik you benefit from:

  • A leader in API contract manufacturing and process development
  • Innovator-focused solutions
  • Experience serving a broad client base including > 5 of the top 10 global pharma companies
  • A strong foundation in synthesis of HPAPI and complex API at all scales
  • A leader in emerging and complex technologies
  • 6 FDA/EU approved commercial scale development and production sites across Europe, US and China
  • A B4B approach with companies large and small to promote greater knowledge exchange, stronger collaboration and active alliances 

Whether you work on pharmaceuticals or are looking to outsource the commercialization of advanced food ingredients, we have the facilities and expertise you are looking for.


Developing and manufacturing APIs and complex intermediates requires experience of advanced synthesis and process development. We offer customized chemical GMP synthesis for small molecule APIs from clinical trials to commercial supply.

Late-phase clinical trials require a scalable process and our experts can advise you on scaling up and work together with you to design process and impurity control strategies. 


Our highly differentiated portfolio of advanced technologies provides you with flexible solutions for even the most complex syntheses of specialized APIs, HPAPIs and intermediates.

We master key synthesis and purification technologies including:

  • Transition metal catalysis: full service from catalyst screen and reaction kinetic models to scale-up and production. Catalyst recycling by organic solvent nanofiltration. Learn more.
  • Cryogenic chemistry: the world’s largest GMP capacity for cryogenic reactions.
  • Amino acid chemistry: one of the world’s most trusted suppliers of pharmaceutical amino acids and dipeptides.
  • Chromatography: small-scale GMP chromatography for ultra-HPAPI to commercial scale GMP chromatography.
  • Biocatalysis: full service from screening to large-scale production.
  • Chiral synthesis: decades of expertise in asymmetric synthesis and chiral resolution.


Alongside our core technological competencies, we also have highly differentiated skills including:

  • Precious Metal Recovery
  • Particle Design
  • Crystal Engineering
  • Chromatography
  • Chemistry in Water
  • Sustainability assessments

A solution provider for innovator-focused HPAPIS

Highly potent active pharmaceutical ingredients (HPAPIs) are a good example of complex APIs that 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 is the world’s largest custom contract manufacturing organization for high potency, anti-cancer and anti-infective APIs, with more than 20 years of expertise in this specialized area. Manufacturing highly potent APIs in large volumes requires extensive project experience with HPAPIs and a strong track record for audits and supply security. Only a few CMOs have the capabilities and experience to turn small-scale development lab quantities to large-scale commercial volumes with batch sizes of over 450 kg. When you plan to produce large volumes of an HPAPI come and see us early on and learn more about our experience and commercial manufacturing capabilities.


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.
