Hydroxy-PEG4-acid is a water-soluble, bifunctional linker featuring a terminal carboxylic acid and a hydroxyl group separated by a four-ethylene glycol unit. This structure enables efficient conjugation to biomolecules while maintaining solubility and stability under physiological conditions.
Hydroxy-PEG4-acid serves as a versatile bifunctional linker for conjugation and solubilization in synthetic chemistry. Its terminal hydroxyl group enables derivatization via esterification or ether formation, while the carboxylic acid facilitates amide coupling or salt formation. The PEG4 spacer provides enhanced solubility and reduced aggregation, making it well-suited for applications in drug delivery systems, peptide modification, and the synthesis of bioconjugates requiring controlled hydrophilicity and stability under physiological conditions.
