AI Overview
COOH-PEG3-COOH (Bis-PEG3-acid, CAS: 31127-85-2) is a homobifunctional, hydrophilic PEG linker with terminal carboxylic acid groups, often used in bioconjugation for modifying proteins, peptides, and drug delivery systems. Available from suppliers like Abbexa, Biopharma PEG, and SINOPEG, it acts as a short PEG spacer (
) to improve water solubility and reduce steric hindrance in molecular, ligand, or nanoparticle studies.
