Boc-PEG4-C2-NHS ester(CAT: I016639) is a heterobifunctional polyethylene glycol (PEG) reagent featuring a Boc-protected amine on one end and an N-hydroxysuccinimide (NHS) ester on the other, separated by a PEG4-C2 spacer. The NHS ester reacts efficiently with primary amines on proteins, peptides, or other biomolecules, while the Boc-protected amine offers orthogonal reactivity after deprotection. The PEG4 spacer enhances solubility, reduces steric hindrance, and provides molecular flexibility, enabling controlled linker design. This reagent is widely used in synthesis chemistry, bioconjugation, and drug delivery research, supporting the development of advanced biomedical materials and precise PEGylation strategies for targeted therapeutic and diagnostic applications.
