Hydroxy-PEG4-CH2COOH is a hydrophilic, 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 or surfaces while maintaining solubility in aqueous environments. The PEG spacer provides steric shielding and reduces non-specific binding.
Hydroxy-PEG4-CH2COOH serves as a versatile bifunctional linker for conjugation and polymer synthesis. The terminal hydroxyl group enables derivatization via esterification or etherification, while the carboxylic acid facilitates amide coupling under standard conditions. Its PEG4 spacer provides enhanced solubility and reduced aggregation, improving performance in bioconjugation and drug delivery applications.
