N-Azido-PEG4-N-Boc-N-PEG3-Boc(Cat No.:I015898)is a multifunctional PEG derivative featuring an azide group, a PEG₄ spacer, and two Boc-protected amines attached through PEG₃ linkers. The azide moiety enables bioorthogonal click chemistry, including copper-catalyzed and strain-promoted cycloadditions, for efficient site-specific conjugation. The Boc-protected amines can be selectively deprotected to generate reactive primary amines for coupling with activated esters, carboxyls, or aldehydes. The PEG linkers enhance solubility, flexibility, and biocompatibility while reducing steric hindrance. This reagent is widely applied in bioconjugation, crosslinking, nanoparticle modification, and advanced drug delivery system development.
