Azide-PEG-amine (MW 2000)

• CAT Number: I045923
• Molecular Weight: 2000(Average)
• Purity: ≥95%

Azide-PEG-Amine (MW 2000)（Cat No.:I045923）is a heterobifunctional polyethylene glycol derivative with a molecular weight of 2,000 Da, containing an azide group at one end and a primary amine at the other. The azide moiety enables efficient click chemistry reactions, including copper-catalyzed or copper-free strain-promoted cycloadditions, while the amine group offers versatile coupling to carboxyl, NHS ester, or aldehyde functionalities. The PEG spacer improves water solubility, stability, and biocompatibility while reducing steric hindrance. This reagent is widely applied in bioconjugation, surface modification, nanomaterials, and targeted drug delivery systems.
