Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports the construction of complex heterocyclic compounds found in drug candidates targeting inflammation, cancer, and central nervous system disorders. The ester and carboxylic acid functional groups allow for easy modification and coupling reactions, making it valuable in medicinal chemistry for building molecular diversity. Also employed in the preparation of pyrrole-based analogs in structure-activity relationship (SAR) studies.
