Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting tyrosine kinases involved in cancer cell proliferation. Shows potential in developing treatments for solid tumors due to its ability to modulate signaling pathways. Also employed in structure-activity relationship (SAR) studies to optimize drug candidates for improved potency and selectivity. Its carboxylic acid functionality allows for further derivatization, enabling the creation of prodrugs or conjugates for enhanced bioavailability.
