Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting tyrosine kinases involved in cancer cell proliferation. Shows potential in developing treatments for solid tumors due to its ability to modulate signaling pathways linked to tumor growth and survival. Also employed in structure-activity relationship (SAR) studies to optimize drug candidates for improved potency and selectivity. Its amide and quinazoline moieties enhance binding affinity to target proteins, making it valuable in designing small-molecule therapeutics.
