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.
