Boc-PEG-Azide

Boc-PEG-azide is a heterobifunctional reagent designed for temporary amine protection and azide-mediated bioorthogonal conjugation (e.g., CuAAC/SPAAC) in peptide and protein engineering. Its key advantages include orthogonal reactivity for sequential modifications, tunable spacer length (n), and compatibility with click chemistry, though the Boc group requires acidic deprotection and the azide may need protection against reduction in complex environments.
