In this episode of the Pharma Matters Podcast, host Ben Locwin speaks with Achim Gsponer, Head of Production at Valsynthese SA, about the challenges and opportunities of working with isoprene—a highly volatile and reactive building block used in specialty chemicals. The discussion explores how Valsynthese safely manages hazardous chemistry in a CDMO setting, from controlling complex Diels–Alder reactions to ensuring reproducibility in multipurpose facilities, and what it takes to turn a difficult raw material “from vapor to value.”
