Quinoline - Applications

Applications

Quinoline is used in the manufacture of dyes, the preparation of hydroxyquinoline sulfate and niacin. It has also used as a solvent for resins and terpenes.

Quinoline is mainly used as a feedstock in the production of other specialty chemicals. Approximately 4 tonnes are produced annually according to a report published in 2005. Its principal use is as a precursor to 8-hydroxyquinoline, which is a versatile chelating agent and precursor to pesticides. Its 2- and 4-methyl derivatives are precursors to cyanine dyes. Oxidation of quinoline affords quinolinic acid (pyridine-2,3-dicarboxylic acid), a precursor to the herbicide sold under the name "Assert".
