Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting receptor tyrosine kinases involved in cancer cell proliferation. Shows potential in the development of antitumor agents due to its ability to modulate signaling pathways in malignant cells. Also employed in structure-activity relationship (SAR) studies to optimize potency and selectivity of indole-based sulfonamide compounds. Its halogenated aromatic structure enhances binding affinity and metabolic stability in drug candidates.
