Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. It plays a role in modulating signaling pathways involved in tumor growth and proliferation. Due to its structural features, it enhances selectivity and binding affinity toward specific protein kinases, making it valuable in developing drugs with improved efficacy and reduced side effects. Also employed in structure-activity relationship (SAR) studies to optimize drug candidates for better metabolic stability and oral bioavailability.
