/paɪˈpɛrɪk/

Origin: A borrowing from Latin, combined with an English element; modelled on a German lexical item. Etymons: Latin piper , -ic suffix.

Etymology: < classical Latin piper pepper n. + -ic suffix, after German Piperinsäure piperic acid (L. H. J. von Babo & E. Keller 1857, in Jrnl. f. prakt. Chem. 72 56).

Chemistry.

piperic acid n. a crystalline bicyclic acid derived from piperine; 5-(1,3-benzodioxol-5-yl)-2,4-pentadienoic acid, (OCH₂O)H₃C₆—(CH)₄—COOH.
