Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its structure supports the development of sulfonamide-based drugs, which are known for antimicrobial and enzyme inhibitory properties. Also employed in the preparation of functionalized polymers and as a building block in organic synthesis where a sulfonamide linker with an aminoethyl group is required. Its hydrochloride form enhances solubility and stability in various reaction conditions.
