Boc-PEG-Acetic acid

Boc-PEG-Acetic acid is a heterobifunctional reagent designed for temporary amine protection and carboxyl-mediated conjugation in peptide synthesis and bioconjugation. Its key advantages include acid-labile Boc deprotection under mild conditions, tunable spacer length (n), and orthogonal reactivity for sequential modifications, though the carboxyl group requires activation for amide bond formation and the Boc group may be unstable in strongly acidic environments.
