A white crystalline substance, C9H6N.OH, of acid properties derived from one of the amido cinnamic acids.

Styrene (which was formerly called cinnamene because obtained from cinnamic acid). See Styrene.

See Cinnamic.

a colorless aromatic oil obtained from cinnamon and cassia, and consisting essentially of cinnamic aldehyde, C6H5.C2H2.CHO. -- Wild cinnamon. See Canella.
