Description

Bis-PEG9-acid features two terminal carboxylic acid groups flanked by PEG9 spacers, offering enhanced solubility and biocompatibility. This bifunctional linker enables efficient conjugation in bioorthogonal workflows and stabilizes peptide or oligonucleotide constructs under physiological conditions.

Application

Bis-PEG9-acid serves as a versatile bifunctional linker for conjugation and polymer synthesis, offering enhanced solubility and stability in aqueous and organic media. Its terminal carboxylic acid groups enable straightforward amide or ester formation under standard coupling conditions, facilitating the construction of PEGylated biomolecules, drug delivery systems, and functionalized surfaces. The nine-ethylene glycol repeat units provide excellent hydrophilicity and resistance to non-specific binding, making it ideal for bioconjugation workflows requiring high biocompatibility and controlled molecular architecture.
