Today is a special day for Aspen Oss, since our company was founded exactly 90 years ago. On July 9th 1923 we began our operations on API production by synthesis of insulin from animal tissue.

Since 1923, we have transformed from a locally operating company to a multinational organization present in many countries worldwide selling our worldclass APIs to national laboratories, R&D start-up companies and big pharma. More information on our history can be found in the chapter ‘Our history’ under the ‘About us’ button on this website.
