This bifunctional PEG linker features carboxylic acid termini on both ends, enabling straightforward conjugation to amine-containing biomolecules or surfaces. The four-ethylene glycol repeat units provide enhanced solubility and reduced non-specific binding, making it ideal for bioconjugation applications in drug delivery and diagnostic development.
HOOCCH₂O-PEG₄-CH₂COOH serves as a bifunctional, water-soluble linker ideal for conjugation and macrocyclic scaffold construction. The terminal carboxylic acid groups enable efficient amide coupling under standard conditions, while the polyether chain provides enhanced solubility and conformational flexibility. This structure facilitates reliable purification and stability in aqueous environments, making it well-suited for applications in peptide-drug conjugates, polymer chemistry, and bioconjugation workflows.
