Supelco Inc Sodium Thioglycolate, 367-51-1, MFCD00043386, 25 G
Supplier: Supelco Inc T063225G
Linear Formula: HSCH2COONa, Molecular Weight: 114.10, Synonym: Mercaptoacetic acid sodium salt, Thioglycolic acid sodium salt, ≥96.5% (iodometric), MP: >300 °C (lit.), storage temp: −20°C. Sodium thioglycolate has been used: as a growth supplement in enrichment media and to study its effect on Arcobacter, in influenza hemagglutinin formulation in order to reduce disulfide-mediated cross-linking and early potency loss, in electron microscopy. At room temperature, concentrations over 70% in water tend to form 1-2% thioglycolides per month which hydrolyze to the original free compound when made acidic or alkaline. The 70% solution oxidizes in air but is stable at room temperature when tightly closed. Thioglycolate salts may also lose purity on storage. The exclusion of air does not materially improve stability.
