Aspen API. High potency & oncology APIs

Aspen API has expertise in manufacturing high potency APIs (HPAPIs) and cytotoxic APIs. Supported by a robust quality system, we produce a high quality product, manufactured in compliance with cGMP, ICH and SHE regulations.


At both Aspen Oss and Fine Chemicals Corporation our HPAPIs are produced in units with OEB 4 and 5 classifications. Aspen API has a long history in working with OEL levels going as low as 0.01 µg/m³. Our heritage in manufacturing complex HPAPIs has enabled Aspen API to establish world class systems and procedures for safe handling of these compounds.

At Fine Chemicals Corporation, cytotoxic product manufacturing is carried out in a dedicated purpose-built facility. Oncology products such as Vinblastine Sulfate and Vincristine Sulfate are manufactured from plant source by unique in-house methods using chromatography.
