Developing & manufacturing complex chemicals

We’ve built a distinguished track record of solving complex chemistry problems for clients around the world. The solutions we’ve delivered for our clients include enzyme inhibitors, vaccine adjuvants and polymeric scaffolds that help advance the treatment of cancers, neurodegenerative, and rare diseases.

Our services include:


We’ve proven that we’re steadfast in helping our clients get to where they want to be.

As carbohydrate and polymer experts, we thrive on tricky chemistry and engineering challenges. We enjoy channelling our creativity by painstakingly mapping out routes to the most intricate molecules.

From route selection to chemistry optimisation, from chemical to chemo-enzymatic methods, we deliver complex molecules at the high standards you need.


We excel in the complex chemistry that makes novel pharmaceutical ingredients.

Our chemical process development and analytical teams are highly skilled. We can ensure safe, rapid, and cost-effective scale-up of your multi-step chemical processes. Our dedicated development scientists are adept at chemical process optimisation.

We make sure our solutions are fit for purpose and set up for success.


We know you need a thorough understanding of your product, and we use our world-class expertise and state-of-the-art analytical equipment to help with this. We want you to go into regulatory submissions with full confidence and can guide you to a successful investigational new drug application.

Our Analytical Services division provides novel assay development, impurity identification, in-process control testing, final product release testing.

We also offer full method validation to meet ICH requirements for active pharmaceutical ingredients in pre-clinical and clinical trials

GMP Manufacturing

Our bespoke cGMP manufacturing facility is where we apply our skills in complex chemistry, scale-up manufacture, and complete rigorous quality assurance. This means we can easily manufacture carbohydrates, biologics, polymers, dendrimers, and small molecules.

True quality assurance is at the heart of our culture. We are licensed to operate under PIC/S PE 009-14 (Part II) (ICH Q7 equivalent) guidelines to deliver predominantly clinical trial active pharmaceutical ingredients (APIs).

What our clients say about us

“When GRO Biosciences was looking for a skilled partner in the synthetic carbohydrate chemistry space, we surveyed a number of firms.  Glycosyn offered us a blend of competence, creativity, and ease of interaction that keeps us coming back for more. 

What started as a single project has now grown into 5 projects across 30 months and counting.  We have dealt with a variety of team members at Glycosyn, all of whom bring strong expertise in their subject matter areas and a commitment to getting the job done.  Given the other partners that we diligenced for our projects, it simply wouldn’t be possible to do with them what we’re doing with Glycosyn.”

Christopher Gregg CSO, GRO Biosciences

“GlycoSyn not only have excellent facilities supported by world class staff but importantly from a client’s perspective, understand the pharmaceutical industry needs and demanding standards from laboratory work through to process design and scale up under GMP.

This, together with not only a “can do” but a “will do” attitude has significantly contributed to our ongoing success.”

Philip Marshall CEO, Oncology Research International Limited

“I’ve had the great fortune to work with GlycoSyn for over 10 years  on projects that span my time at Spinifex Pharmaceutical and Starpharma.

In all their work for me they have demonstrated a very high level of technical proficiency as they developed scalable synthetic routes to APIs and intermediates and executed cGMP campaigns. Their facility is first-class and is supported by an excellent analytical chemistry group and a robust quality assurance system.

What sets GlycoSyn apart is they do more than just ‘fee-for-service’ work; they commit to a project as if it were their own.”

Tom McCarthy CEO, Spinifex Pharmaceuticals
