GlycoSyn: A quality achiever, a safe pair of hands

GlycoSyn is a world leader in the development and manufacture of active pharmaceutical ingredients (API’s) for pre-clinical and clinical trials, ranging from conventional small molecules to dendrimers and complex oligosaccharides. We also undertake custom specialty manufacture of commercial ingredients under contract. With the world’s largest combined concentration of carbohydrate chemistry and GMP manufacturing expertise, we are best known for our ability to solve complex problems for clients worldwide, and for our dedication to extending discovery frontiers in the pharmaceutical industry.

Safety and quality are vitally important to us. But we also have a good head for business. We fiercely guard clients’ intellectual property. Our “right first time” approach helps large and small clients gain a competitive advantage by reducing time to market and alleviating the technical and regulatory risks associated with drug development.

We have been involved in carbohydrate chemistry and multi-synthesis on our Wellington site since 1985 and GMP manufacture since 2003. We are based in New Zealand, but our strong track record, our solid US client base and effective international partnerships  put us at the very heart of the global industry. What’s more, we are a fun, nimble and transparent organization, driven by a “can-do” pioneering Kiwi spirit, and a friendly, easy-access approach with a strong work ethic. So working with us is easy!

"No chemistry is too tricky, no engineering challenge too demanding, and no manufacture too small. We’re highly motivated and passionate about chemistry and pharmaceutical development. It’s what gets us out of bed in the mornings."

Our Services

GlycoSyn provides synthetic route evaluation and development, process development, kilogram scale non-GMP and GMP manufacture of investigational new drugs and specialty commercial ingredients under contract to pharmaceutical companies around the globe.

Research (Rational design, custom synthesis and route optimization)

Our highly experienced Research division provides custom synthesis services on a fee-for-service basis and can be engaged to assist with the selection, optimization and small-scale syntheses of lead drug candidates.

Process Development (Process optimization and pilot-scale manufacture)

Our safe, speedy scale-up of multi-step chemical processes provides clients with larger quantities of APIs for pre-clinical evaluation with full supporting documentation to facilitate regulatory submissions.

Analytical Services (Method development, stability studies)

For in-process control, product release and stability data, as well as full analytical method development and validation to meet ICH requirements for APIs.

GMP Manufacture (Carbohydrates, multi-step synthesis, small molecules, dendrimers)

We manufacture APIs by chemical synthesis at any scale for pre-clinical or clinical trials and specialty commercial applications in our state-of-the art, licensed GMP manufacturing facilities.

Online Sales (Carbohydrates, inositols, azasugars)

GlycoSyn also sells a range of high-quality specialty chemicals and natural products via our online catalogue.
