Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting kinase inhibitors. Its dual sulfonyl groups enhance binding selectivity, making it valuable in developing anti-inflammatory and anticancer agents. Commonly employed in structure-activity relationship (SAR) studies to optimize drug potency and metabolic stability. Also utilized in the preparation of sulfonamide-based protease inhibitors. Its rigid aromatic framework supports conformational control in drug design.
