Propionyl chloride (CAS 79-03-8) is an acyl chloride used primarily in organic synthesis to introduce propionyl groups in esters, amides, and ketones. It is also employed as an intermediate in pharmaceuticals and agrochemical production. This high-purity reagent (CH₃CH₂COCl, MW 92.52) is stored at ambient conditions but requires careful handling due to its corrosive and reactive nature (Signal Word: Danger). Molekula supplies Propionyl chloride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

This substance is available from Molekula on enquiry. Full specification, Safety Data Sheet and Certificate of Analysis documentation are provided with your quotation once our team confirms the grade and pack size you need.
