Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the formation of biologically active molecules that target specific signaling pathways in tumor cells. Also employed in research settings to design new heterocyclic compounds with potential antiviral and anti-inflammatory properties. The carboxylic acid and keto functionalities allow for easy derivatization, making it valuable in medicinal chemistry for structure-activity relationship studies.
