Hydroxy-PEG3-acid is a water-soluble, bifunctional linker featuring a terminal carboxylic acid and hydroxyl group separated by a three-ethylene glycol unit. This structure enables conjugation to biomolecules via amine-reactive coupling while maintaining solubility and stability under physiological conditions.
Hydroxy-PEG3-acid serves as a versatile bifunctional linker for conjugation and solubilization in synthetic chemistry. The terminal hydroxyl group enables derivatization via esterification or ether formation, while the carboxylic acid facilitates amide coupling or salt formation. Its three-ethylene glycol unit provides enhanced aqueous solubility and stability, making it ideal for bioconjugation, peptide modification, and the synthesis of functionalized polymers and drug delivery systems.
