CatSci was formed in December 2010, after our Founders saw an opportunity in the market for a unique catalyst screening company. They spun CatSci out of AstraZeneca, setting up the same high laboratory standards and equipment, quickly becoming established experts in catalyst screening. Subsequently, it became clear that the market required more and so we broadened our offerings from catalytic chemistry to providing customised chemistry R&D services for emerging, mid-sized and large pharma organisations worldwide.

We have gathered extensive knowledge through working on hundreds of reactions and processes addressing drug substance needs for small and large pharmaceutical companies. This helps us to refine workflows based on world-leading approaches. Our passion for science and innovative thinking means we will expedite the progress of your drug projects.
