Cinnamoyl chloride (Cat No.: M070435) is an aromatic acid chloride derived from cinnamic acid, characterized by a phenyl group attached to an α,β-unsaturated acyl chloride moiety. This pale yellow to colorless liquid is highly reactive, making it a valuable intermediate in organic synthesis. It is commonly used to prepare cinnamides, esters, and other derivatives in pharmaceutical, fragrance, and polymer research. Its conjugated double bond and reactive chloride group enable efficient acylation reactions under mild conditions, making it versatile in fine chemical production.
