Arklow, Ireland Facility Overview

Commercial Scale, Generic API & Advanced Intermediate Manufacturing

Our Arklow (Ireland) site is our primary center for cGMP production of commercial and late-stage APIs and Advanced Intermediates. The 64,000 m2 complex supports customers with expertise in new process evaluation, process development validation and technology transfer. The site is also equipped with one of the few large-scale Simulated Moving Bed (SMB) chromatography units for chiral separation and continuous chromatography purifications.



Our facility features four separate cGMP compliant, FDA and HPRA inspected plants, and has a total reactor capacity of over 100,000 L.
