Medchemexpress LLC Thiol-PEG1-acid | 1260092-48-5 | 95.0% | 150.20 g/mol | C5H10O3S | 5 MG
Thiol-PEG1-acid is a short polyethylene glycol linker bearing a thiol (-SH) and a terminal carboxyl (-COOH). It serves as a bifunctional reagent for chemical biology and bioconjugation applications that require a small, hydrophilic spacer with orthogonal reactive handles.
- Contains a reactive thiol (-SH) functional group for selective conjugation.
- Terminal carboxyl group enables amide or ester bond formation with amines or alcohols.
- Short PEG spacer improves solubility and reduces steric hindrance in conjugates.
- Typical purity listed as 95.0%.
- Soluble in DMSO at 100 mg/mL; may require ultrasonic assistance.
- Stable as a pure material at -20°C for up to 3 years; in solution store at -80°C for extended stability.
