General description

Benzothiazole-6-carboxylic acid (BTCA) is a benzothiazole derivative.

Application

Benzothiazole-6-carboxylic acid may be used in the synthesis of N-(pyridin-4-yl)benzo[d]thiazole-6-carboxamide, which shows the potential to inhibit K1 capsule formation in uropathogenic Escherichia coli. It may also be used as an internal standard during the quantification of benzothiazoles by liquid chromatography-electrospray ionization-tandem mass spectrometry.

The first method for the determination of commonly used corrosion inhibitors in environmental water samples by liquid chromatography-electrospray ionization-tandem mass spectrometry is presented. Benzotriazole (BTri) and the two isomers of tolyltriazole (5- and 4-TTri) are separated in an isocratic run.
