Our value proposition

Our Way

The company founder, Joseph Rohner, believed that ongoing change was vital to progress. And it is a philosophy that our 200 highly skilled staff uphold to the present day - from the production of formic acid, to the development and global marketing of textile dyes, state-of-the-art performance chemicals and active pharmaceutical ingredients (API). As a mid-sized company based in Pratteln near Basel, with a history of more than 100 years, we combine proven skills in custom manufacturing with a traditional Swiss commitment to quality. We serve demanding customers in growth markets – proving them with development and rapid scale-up of complex, multi-step synthetic processes.
