Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting kinase inhibition. Its structure supports the development of drugs that modulate cellular signaling pathways, especially in oncology research. The compound's sulfonamide and amine functionalities enhance binding selectivity and solubility, making it valuable in optimizing drug candidates for improved efficacy and pharmacokinetics. Also employed in the preparation of proteolysis-targeting chimeras (PROTACs) due to its ability to link target-binding moieties with E3 ligase ligands.
