Cbz-NH-PEG6-C2-acid(CAT: I016365) is a versatile PEGylated linker designed for advanced chemical synthesis and bioconjugation applications. The molecule features a carbobenzoxy (Cbz) protected amine, a six-unit polyethylene glycol (PEG6) spacer, and a terminal carboxylic acid group. The PEG6 chain imparts water solubility, flexibility, and reduced steric hindrance, making it ideal for connecting biomolecules, peptides, or drugs. Its carboxyl group enables efficient coupling to amines or other reactive sites, while the Cbz group provides controlled protection and deprotection. This reagent is frequently used in drug discovery, antibody–drug conjugates, and material science research, supporting customizable linker strategies in molecular design.
