Azide Reagents

Azide reagents in Uniform mPEG (methoxy polyethylene glycol) Modifiers are PEG molecules terminated with an azide (-N₃) group, enabling selective conjugation via copper-catalyzed or copper-free Click Chemistry with alkyne-functionalized targets. These reagents provide a stable, bioorthogonal method for attaching PEG to biomolecules, nanoparticles, or surfaces without interfering with native biological functions. The uniformity of mPEG ensures consistent solubility, reduced immunogenicity, and enhanced pharmacokinetic properties in drug delivery, diagnostics, and bioconjugation applications.
