Quinoline-2-carboxylic acid, also called quinaldic acid, is a heterocyclic aromatic compound primarily used in organic synthesis, pharmaceutical intermediates, and as a building block for agrochemicals. Its structure combines a quinoline core with a carboxylic acid group, enabling versatile reactivity in chemical transformations. In analytical chemistry, it serves as a reagent for assaying copper, zinc and uranium, because it forms insoluble salts with these metals. This chemical has a CAS number of 93-10-7, a molecular formula of C10H7NO2, and a molecular weight of 173.17 g/mol. It is stable under ambient storage conditions but requires careful handling, as indicated by its **Warning** signal word. Molekula supplies quinoline-2-carboxylic acid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
