N-(Aminooxy-PEG3)-N-bis(PEG4-Boc)（Cat No.:I014495）is a multifunctional PEG-based reagent featuring an aminooxy group linked via a three-unit PEG chain and two Boc-protected PEG4 arms. The aminooxy group enables chemoselective oxime ligation with aldehydes or ketones, providing stable conjugation under mild conditions. The Boc groups protect terminal amines, allowing controlled deprotection for selective coupling. The PEG chains enhance solubility, flexibility, and biocompatibility while minimizing steric hindrance. This reagent is valuable in peptide chemistry, drug discovery, and bioconjugation, supporting the design of multifunctional linkers, biomolecule modification, and advanced therapeutic or diagnostic constructs.
