Quinoline, any of a class of organic   compounds of the aromatic heterocyclic series characterized by a double-ring   structure composed of a benzene and a pyridine ring fused at two adjacent   carbon atoms. The benzene ring contains six carbon atoms, while the pyridine ring   contains five carbon atoms and a nitrogen atom. The simplest member of the   quinoline family is quinoline itself, a compound with molecular structure   C9H7N.

Quinoline is used principally for the   manufacture of nicotinic acid, which prevents pellagra in humans, and other   chemicals. Several methods are known for its preparation, and production of   synthetic quinoline exceeds that from coal tar.

Several alkaloids (alkaline organic   compounds produced in plants) are members of the quinoline family; these   include quinine and other derivatives from the cinchona tree. The   antimalarial drugs chloroquine, mefloquine, and amodiaquin are synthetic   quinoline compounds, as are dibucaine hydrochloride, a long-acting local   anesthetic that is commonly used as a topical agent to relieve pain from   minor cuts and insect bites and stings, and cyanine, the oldest of an   important class of dyes.
