α-Formyl-ω-mercapto poly(ethylene glycol) is a bifunctional PEG derivative synthesized via ring-opening polymerization of ethylene oxide followed by selective functionalization. It serves as a critical linker in bioconjugation, featuring an aldehyde group for Schiff base formation and a thiol for maleimide coupling. CAS: 160749-28-2.
Store under inert atmosphere at -20°C to prevent oxidation. Use with appropriate respiratory protection due to potential sensitization risks. Avoid contact with strong oxidizing agents.
