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 design of compounds that can selectively target signaling pathways involved in tumor growth. Also employed in medicinal chemistry research to build heterocyclic frameworks with potential antiviral and anti-inflammatory activity. The carboxylic acid functionality allows for easy derivatization, enabling the creation of amide or ester analogs during drug optimization.
