Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted benzoic acid derivatives. Its functional groups—bromo, methoxy, nitro, and carboxylic acid—allow for selective transformations, such as cross-coupling reactions via the bromo group, reduction of the nitro group to an amine, or esterification of the acid. Commonly employed in research settings to build complex aromatic structures for drug discovery and in the preparation of herbicides and fungicides.
