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 (APIs). As a mid-sized company based in Pratteln, near Basle, we combine proven skills in custom manufacturing with a traditional Swiss commitment to quality. Against this background, we have invested more than 200 million Swiss francs in our plants and equipment in the last decade alone. Whether liquid crystals, nanotechnology, functional polymers or, our particular core competency, Transition Metal Catalysis (TMC), we serve demanding customers in growth markets – providing them with rapid scale-up of complex, multi-step synthetic processes.
