Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of selective herbicides. It plays a role in the development of chlorinated aromatic compounds due to its reactive chlorine and carboxylic acid functional groups. Its methoxy and carboxylic acid groups allow for further chemical modifications, making it valuable in research and development of bioactive molecules. Commonly handled as a solution to improve reactivity and ease of dosing in industrial processes.
