m-PEG3-CH2CH2COOH features a mid-chain PEG3 spacer flanked by reactive terminal functionalities: a methylene-linked carboxylic acid for conjugation and an ether-tethered hydrophilic chain. This structure enables stable, water-soluble linkages in bioconjugation workflows, facilitating efficient coupling to amine-bearing biomolecules under mild conditions.
m-PEG3-CH2CH2COOH serves as a versatile bifunctional linker for conjugation and polymer synthesis, combining the solubility and biocompatibility of PEG with a reactive carboxylic acid terminus. It enables efficient amide bond formation under standard coupling conditions, facilitating site-specific attachment to amines in peptides, proteins, or biomolecules. The triethylene glycol spacer provides enhanced flexibility and hydrophilicity, improving solubility and reducing non-specific binding in biological applications.
