Amine-PEG-CH₂COOH (MW 3400)(Cat No.:I045927)is a heterobifunctional polyethylene glycol derivative with a molecular weight of 3,400 Da, bearing a primary amine at one end and a carboxylic acid at the other. The amine group enables coupling to carboxyl, NHS esters, or aldehydes, while the terminal carboxyl group reacts with amines or hydroxyls via standard coupling strategies. The PEG spacer enhances water solubility, flexibility, and biocompatibility, reducing steric hindrance and nonspecific interactions. This reagent is widely used in bioconjugation, polymer modification, nanoparticle functionalization, and targeted drug delivery applications.
