Used as a key intermediate in the synthesis of indole-based pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its sulfonamide and hydroxyl functional groups enable strong binding to biological targets, enhancing selectivity and potency. Also employed in research for designing anti-inflammatory and antiproliferative agents due to its ability to modulate cellular signaling pathways. The compound’s structure supports derivatization for optimizing drug-like properties in medicinal chemistry programs.
