Description

Bis-PEG5-acid features two terminal carboxylic acid groups flanked by PEG5 chains, offering enhanced solubility and flexibility. This bifunctional linker enables efficient conjugation in bioconjugate chemistry, streamlining the creation of polymer-drug hybrids and surface-tethered biomolecules under standard conditions.

Application

Bis-PEG5-acid serves as a versatile bifunctional linker for conjugation and polymer synthesis, enabling efficient coupling of biomolecules, drugs, or functionalized surfaces via amine-reactive ester groups. Its five-ethylene glycol units provide enhanced solubility and reduced non-specific binding, while the terminal carboxylic acids facilitate straightforward derivatization under standard coupling conditions. Ideal for modular synthesis in drug delivery systems and bioconjugate applications.
