Propionyl chloride (CAS 79-03-8) is a reactive acylating agent with the molecular formula C3H5ClO. It is industrially produced via the chlorination of propionic acid or reaction with thionyl chloride, serving as a key intermediate for synthesizing pharmaceuticals and agrochemicals.
Strictly store in sealed, dry containers under inert atmosphere. Requires corrosive material handling protocols due to hydrolysis releasing HCl gas; personal protective equipment including face shields and chemical-resistant gloves is mandatory.
