Synonyms: Thiol-PEG-Thiol; SH-PEG-SH; Thiol-polyethylene glycol-Thiol; SH-polyethylene glycol-SH

SH-EG-SH is a linear homobifunctional PEG containing reactive free sulfhydryl groups at both ends of the molecular chain. HS-PEG-HS can selectively react with maleimide and transition metal surfaces (e.g., gold, silver, etc.) by means of sulfhydryl groups free at both ends of the molecular chain. Meanwhile, the free sulfhydryl groups in the molecular chain segment can be easily oxidized and polymerized by the S-S disulfide bond in the air and reversed by reducing agent. It is a useful reagent for reversible crosslinking of PEG. Its applications include: decoupling, drug delivery, PEG hydrogel's, cross-linking agents, and surface functionalization.
