Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its rigid heterocyclic scaffold, which enhances binding selectivity and metabolic stability in drug candidates. Also employed in the preparation of modulators for central nervous system disorders, including anxiolytics and antipsychotics, leveraging its ability to interact with neurotransmitter receptors. Its carboxylic acid functionality allows for easy derivatization, enabling the formation of amides and esters in structure-activity relationship studies.
