I. [Product Description]
CBZ-NH-PEG-COOH (Carbobenzyloxy-Amino-Polyethylene Glycol-Carboxyl) is a multifunctional organic intermediate, possessing the characteristics of both pharmaceutical intermediates and polymer modification materials. The carbobenzyloxy (CBZ) in its core structure provides a protecting group function. The amino and carboxyl groups can achieve directional coupling, and the PEG segment imparts excellent water solubility and biocompatibility, making it suitable for catalytic reaction systems and complex molecular construction.
