Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its structure enables functionalization for creating biologically active molecules. It is also employed in the preparation of heterocyclic compounds with potential antimicrobial and antifungal properties. Due to the presence of reactive chlorine and carboxylic acid groups, it serves as a building block in medicinal chemistry for coupling reactions and scaffold modification.
