Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its structure supports the creation of compounds with biological activity, especially in agrochemical research. It is also employed in medicinal chemistry for designing heterocyclic compounds that exhibit potential enzyme inhibitory effects. Commonly utilized in reactions where carboxylic acid functionality allows for coupling with amines or alcohols to form amides or esters, enhancing molecular diversity for screening in drug discovery.
