Propionyl Chloride
Propionyl Chloride (CAS: 79-03-8) is a colorless, pungent, fuming liquid acyl chloride used to introduce the propionyl group into alcohols, amines, and other nucleophiles. It is a key intermediate for propionate esters, pharmaceuticals such as analgesics and antibiotics, agrochemicals, flavors, and fragrance ingredients. The compound reacts readily at moderate temperatures, enabling efficient acylation without harsh conditions, and it is consumed in a wide range of fine-chemical processes. It is moisture-sensitive and is typically stored and shipped in dry, sealed systems with nitrogen padding to maintain quality. Buyers value its high reactivity, clean conversion, and the dependable supply that supports continuous production of propionyl-derivative products.
• Acylation reagent: introduces the propionyl group into alcohols, phenols, and amines to form esters and amides under mild conditions.
• Pharmaceutical intermediate: used in the synthesis of active ingredients including analgesics, antibiotics, and CNS agents.
• Agrochemicals: a building block for herbicide and pesticide intermediates that improve crop-protection performance.
• Flavors and fragrances: produces propionate esters used as flavor and aroma components in food and perfumery.
