Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly those targeting tyrosine kinases involved in cancer cell proliferation. Shows potential in the development of targeted therapies for solid tumors and hematological malignancies. Also employed in studies exploring blood-brain barrier penetration for central nervous system-active drugs due to its structural properties. Commonly utilized in structure-activity relationship (SAR) studies to optimize potency and selectivity in drug candidates.
