Azido-PEG12-amine is an azide-terminated polyethylene glycol (PEG12) linker bearing a terminal primary amine used in bioconjugation and click-chemistry applications.

• Azide group enables click chemistry (azide-alkyne cycloaddition).
• Terminal primary amine reacts with carboxylic acids, activated NHS esters, and carbonyls.
• PEG12 spacer increases aqueous solubility and reduces steric hindrance.
• Molecular weight 614.73; formula C26H54N4O12.
• High purity (98.0% by NMR) with 1H NMR and MS consistent with structure.
• Storage: sealed, away from moisture and light; in solvent store at -80°C (6 months) or -20°C (1 month).
