/ˈkɪnəlɪn/, 1800s– quinolein, 1800s– quinoleine, 1800s– quinolene, 1800s– quinoline.

Origin: A borrowing from German. Etymon: German Chinolin.

Etymology: < German Chinolin (C. Gerhardt 1842, in Ann. der Chem. u. Pharm. 42 311) < China quina n. + -ol -ol suffix + in -ine suffix⁵. Compare French quinoléine (1843).

Chemistry.

A pungent, colourless, heterocyclic liquid present in coal tar and used in the manufacture of dyes, in chemical synthesis, and as a solvent.Quinoline has a bicyclic molecule consisting of fused benzene and pyridine rings. Formula: C₉H₇N.
