Used in pharmaceutical research as a key intermediate in the synthesis of selective kinase inhibitors, particularly those targeting neurodegenerative diseases and certain cancers. Its structure supports blood-brain barrier penetration, making it valuable in developing central nervous system (CNS) therapeutics. Also employed in the optimization of drug candidates requiring enhanced metabolic stability and binding affinity due to the presence of trifluoromethyl and chloro substituents. Commonly utilized in structure-activity relationship (SAR) studies to improve potency and selectivity.
