Cas no 42105-26-0 (but-3-yn-2-amine hydrochloride)

But-3-yn-2-amine hydrochloride is a hydrochloride salt derivative of but-3-yn-2-amine, featuring a terminal alkyne group and an amine functionality, making it a versatile intermediate in organic synthesis. Its reactive alkyne moiety enables click chemistry applications, particularly in Cu(I)-catalyzed azide-alkyne cycloadditions (CuAAC), while the amine group allows for further derivatization. The hydrochloride form enhances stability and solubility in polar solvents, facilitating handling and storage. This compound is useful in pharmaceutical research, material science, and bioconjugation, where precise functional group manipulation is required. Its structural features make it valuable for constructing complex molecular architectures.
