- Description
COOH-PEG3-NH2.HCl is a bifunctional PEG derivative supplied as the hydrochloride salt, with amino and carboxyl functionality connected through a hydrophilic PEG3 spacer. The spacer promotes water solubility for bioconjugation work. The amino group supports coupling with activated esters or carbonyl compounds, including reductive amination, while the carboxyl group can undergo activated coupling with primary amines to form amide bonds. These complementary functionalities support biomolecule modification and pharmaceutical synthesis.
