Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. It serves as a building block for compounds that modulate protein kinases involved in cell signaling, proliferation, and apoptosis. Its structure allows functionalization at multiple sites, enabling the development of selective inhibitors for tyrosine kinases and other enzyme targets. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize potency and selectivity in drug candidates. Also utilized in the preparation of fluorescent probes and labeled compounds for biochemical assays.
