Thiol-PEG1-acid (SH-PEG1-COOH) is a short polyethylene glycol derivative with a terminal thiol and a carboxylic acid. It functions as a bifunctional linker reagent for bioconjugation, enabling selective thiol coupling and formation of amide or ester bonds at the carboxyl terminus. Typical applications include linker synthesis, surface modification, and conjugation to peptides, proteins, or surfaces. Purity is typically 95%.

  • Provides a terminal thiol for selective thiol coupling reactions.
  • Offers a carboxyl group for amide or ester bond formation.
  • Short PEG spacer minimizes steric hindrance in conjugates.
  • Soluble in DMSO (approx. 100 MG/ML) for convenient stock solutions.
  • Store pure material at -20°C; in solvent store at -80°C for extended stability.
