Cas no 105800-42-8 (Benzenesulfonamide, 4-ethynyl-N,N-dimethyl-)
Benzenesulfonamide, 4-ethynyl-N,N-dimethyl-, is a specialized organic compound featuring a benzenesulfonamide core substituted with an ethynyl group at the para position and dimethylamine functionality on the sulfonamide nitrogen. This structure imparts unique reactivity, particularly in click chemistry applications, where the ethynyl group serves as a versatile handle for copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. The dimethylsulfonamide moiety enhances solubility and stability, making it suitable for use in pharmaceutical intermediates, materials science, and bioconjugation. Its well-defined reactivity profile and compatibility with diverse synthetic conditions make it a valuable building block for constructing complex molecular architectures.
