    In the 1840’s, Emil Mallinckrodt bought an apple orchard in St Louis Missouri. About 27 years later, his sons founded a chemical company called Mallinckrodt on that same land and it has been in continuous production since. This site along with two other manufacturing facilities now comprise all API manufacturing for Mallinckrodt Pharmaceuticals and are key components of our long earned reputation for high quality and reliability.

Over our 142-year history, Mallinckrodt has earned a reputation for quality and dependability in the fine chemical industry and continues that strong tradition today in APIs.
