quinoline

[′kwin·ə‚lēn] (organic chemistry) C₉H₇N Water-soluble, aromatic nitrogen compound; colorless, hygroscopic liquid; also soluble in alcohol, ether, and carbon disulfide; boils at 238°C; used in medicine and as a chemical intermediate. Also known as chinoline; leucoline; leukol.

Quinoline

(2,3-benzopyridine), a heterocyclic compound. Quinoline is a colorless liquid with a characteristic sweetish odor and a boiling point of 238°C.

It is poorly soluble in water and readily soluble in alcohol and ether. It is a weak base and with acids forms salts, such as C₉H₇N·HCl. With alkyl halides, it forms quinolinium tertiary salts. Quinoline is found in coal tar, from which it is extracted together with isoquinoline. Synthetic quinoline is obtained by the Skraup reaction (seeSKRAUP SYNTHESIS). Quinoline is used as a solvent for sulfur and phosphorus and in the decarboxylation of aromatic acids and other reactions. Many alkaloids, such as quinine and fagarine, and drugs, such as Atophan (cinchophen), Entero-Septol (iodochlorhydroxyquin), chloroquine, and primaquine, are derivatives of quinoline, as are several cyanine dyes and analytical reagents, such as 8-hydroxyquinoline.

quinoline

[kwin´o-lēn] an amine or alkaloid derivable from quinine, coal tar, and various other sources, which has antiseptic, antipyretic, and antimalarial properties.

quin·o·line

(kwin'ō-lēn, -lin), 1. A volatile nitrogenous base obtained by the distillation of coal tar, bones, alkaloids, and other substances; a basic structure of many dyes and drugs; also used as an antimalarial. Synonym(s): chinoleine, leucoline2. One of a class of alkaloids based on the quinoline (1) structure.
