Ms-PEG2-C2-Boc（Cat No.:I016002）is a heterobifunctional polyethylene glycol reagent featuring a mesylate (Ms) leaving group on one end and a Boc-protected amine on the other, separated by a two-unit PEG chain and a two-carbon (C2) spacer. The mesylate group enables efficient nucleophilic substitution, while the Boc-protected amine provides controlled deprotection for selective conjugation. The PEG2-C2 backbone enhances solubility, flexibility, and reduces steric hindrance, supporting efficient bioconjugation. This reagent is widely applied in peptide synthesis, drug discovery, and materials science to create multifunctional biomolecules, linkers, and therapeutic or diagnostic platforms.
