Brit.

/ˌəʊpɪˈanɪk/, U.S.

/ˌoʊpiˈænɪk/

Origin: Formed within English, by derivation. Etymons: opiane n., -ic suffix.

Etymology: < opiane n. + -ic suffix. In sense 1 as opianic acid after German Opiansäure (J. Liebig & F. Wöhler 1842, in Ann. der Chem. u. Pharm. 44 126). In sense 2 as opianic ether after German Opianäther (F. Wöhler 1844, in Ann. der Chem. u. Pharm. 50 5). Compare French opianique (1889 in Littré).

Chemistry.

1. opianic acid n. a crystalline aldehydic aromatic acid obtained from the oxidation of narcotine; 6-formyl-2,3-dimethoxybenzoic acid, C₁₀H₁₀O₅.
