Boc-PEG-NHS ester
Boc-PEG-NHS ester is a heterobifunctional reagent designed for temporary amine protection and efficient NHS ester-mediated conjugation in peptide synthesis and bioconjugation. Its key advantages include orthogonal reactivity for sequential modifications, rapid amine coupling under mild conditions, and tunable spacer length (n), though the NHS ester requires anhydrous handling due to hydrolysis sensitivity and the Boc group needs acidic conditions for deprotection.
