Propionüülkloriid

Propionüülkloriid is an organic compound with the chemical formula CH3CH2COCl. It is a colorless liquid with a pungent odor and is classified as an acyl chloride. Propionüülkloriid is derived from propionic acid, where the hydroxyl group is replaced by a chlorine atom.

This compound is highly reactive, particularly with nucleophiles. It readily undergoes hydrolysis in the presence of water to form propionic acid and hydrochloric acid. Propionüülkloriid is also used in acylation reactions, where it introduces the propionyl group (CH3CH2CO-) into other molecules. This reactivity makes it a valuable reagent in organic synthesis, serving as an intermediate in the production of various esters, amides, and ketones.

Due to its corrosive nature and tendency to release hydrochloric acid upon contact with moisture, propionüülkloriid must be handled with appropriate safety precautions in well-ventilated areas. It is typically stored in tightly sealed containers to prevent exposure to air and moisture. Its applications are primarily found in chemical laboratories and industrial manufacturing processes where controlled acylation is required.
