Customized API development and manufacturing services


We are an industry-leading integrated development and manufacturing service provider for small molecule drug substances and their intermediates.

Chemistry is core to us. Our track record in route scouting, developing and manufacturing API and intermediates extends back to the genesis of contract development and manufacturing. Thousands of compounds have been successfully developed and progressed by our R&D, process development and manufacturing teams. Many of these molecules have been scaled under accelerated timelines to meet program objectives. 

We recognize that chemical synthesis accounts for the majority of the drugs on the market today, as well as in the drug development pipeline. And we recognize that today’s drug compound candidates are increasingly complex, with many API candidates requiring specialized handling and protocols.  That’s why we offer flexible API development and manufacturing services, inclusive of solid form selection and particle engineering, to meet target product profiles across a wide range of chemical synthesis.

We also appreciate that every drug program is different and our customers require more agility and adaptiveness than ever before. We continue to meet the challenges of phase-appropriate drug substance manufacturing through our investments in world-class infrastructure, technologies and teams to support your small molecule needs from proof of concept through commercialization.
