6-Azido-hexylamine（Cat No.:I044634）is a bifunctional alkyl azide containing a terminal primary amine and an azide group separated by a six-carbon aliphatic chain. The amine group enables coupling to carboxylic acids or activated esters via amide bond formation, while the azide group participates in bioorthogonal click chemistry, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC). Its flexible hexyl linker provides spatial separation between functional groups, making it suitable for synthesizing heterobifunctional linkers, crosslinkers, and labeling agents. Commonly used in bioconjugation, chemical biology, and materials science for precise molecular modification.
