Description

2-Butyn-1-amine, hydrochloride delivers a reactive alkyne handle and primary amine functionality in a single, bench-stable salt form. This bifunctional scaffold enables efficient conjugation workflows in click chemistry, bioconjugation, and polymer synthesis under standard conditions. The protonated amine enhances solubility in aqueous media while preserving alkyne integrity for downstream transformations.

Application

2-Butyn-1-amine, hydrochloride serves as a versatile building block in synthetic organic chemistry, enabling efficient access to conjugated enamine and amide derivatives via nucleophilic addition or coupling reactions. Its terminal alkyne functionality supports reliable copper-catalyzed azide-alkyne cycloaddition (CuAAC) for triazole formation, while the primary amine group facilitates straightforward derivatization. The hydrochloride salt enhances bench stability and simplifies handling, making it well-suited for multistep synthesis and high-throughput screening workflows.
