Thiol-PEG1-acid is a short polyethylene glycol (PEG) linker bearing a thiol (-SH) and a terminal carboxyl (-COOH). It is used as a bifunctional coupling reagent in bioconjugation and small-scale synthesis where selective thiol reactivity and carboxyl-mediated coupling are required.
- Short PEG linker with terminal thiol and carboxyl functional groups.
- Enables selective coupling via thiol chemistry, such as maleimide conjugation.
- Carboxyl group suitable for amide or ester bond formation with amines or alcohols.
- Low molecular weight (approx. 150.2 g/mol) for minimal steric hindrance.
- Typically supplied at 95.0% purity for research applications.
- Useful for bioconjugation, linker construction, and small-molecule linker design.
