Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. Shows potential in modulating signaling pathways involved in tumor growth and cell proliferation. Currently investigated for its role in developing treatments for solid tumors and hematologic malignancies due to its ability to enhance selectivity and potency in inhibitor compounds. Also employed in structure-activity relationship (SAR) studies to optimize drug candidates for improved metabolic stability and bioavailability.
