2-Quinolinecarboxylic acid

???? C??? ??, ??, ??

??? ??

light brown needle-like crystalline powder

??

For the determination of copper, zinc and uranium with which it forms insoluble salts.

??

ChEBI: A quinolinemonocarboxylic acid having the carboxy group at the 2-position.

?? ??

Quinaldic acid is also referred as quinoline-2-carboxylic acid. Microwave-assisted preparation of substituted anilides of quinaldic acid has been reported. It inhibits the oxidation of pyruvate, α-ketoglutarate, glutamate and citrate in rat liver mitochondria. Quinaldic acid is a metabolite of tryptophan degradation and inhibits the gluconeogenesis in perfused livers.

Purification Methods

Crystallise quinaldic acid from *C6H6 or AcOH. It is used for the estimation of many metals. The methyl ester has m 86-87o (from hexane) and pK25 1.76. [Chauduri et al. Frez Z Anal Chem 281 361 1976, Beilstein 22 H 71, 22 II 55, 22 III/IV 1149, 22/3 V 183.]
