α-Succinimidyl-ω-hydroxyl poly(ethylene glycol) is a heterobifunctional PEG derivative featuring an NHS ester at one terminus and a hydroxyl group at the other. This structure enables efficient conjugation with primary amines on biomolecules via amide bond formation while retaining a reactive hydroxyl site for further modification. The standard molecular formula corresponds to CxHyNzOw, though specific CAS numbers vary by average molecular weight (MW).
