Product Name:L-Ascorbic acid 2-sulfate disodium salt dihydrate
English Name:L-Ascorbic acid 2-sulfate disodium salt dihydrate
CAS No.:53910-28-4
Aliases:L-Ascorbic acid 2-sulfate disodium salt, Ascorbyl sulfate disodium salt, 2-Sulfo-L-ascorbic acid disodium salt, Vitamin C 2-sulfate disodium salt
Molecular Formula:C6H6Na2O9S·2H2O
Physical Properties:White to off-white crystalline powder, usually existing as dihydrate; freely soluble in water, slightly soluble in ethanol, practically insoluble in chloroform and ether; pH of 2% aqueous solution is about 6.0–7.5; hygroscopic, decomposes at approximately 200°C; should be stored in a sealed, cool, dry place protected from light.
Uses:It is a sulfated derivative of vitamin C that retains the physiological activity of ascorbic acid while exhibiting significantly improved stability and water solubility. It is widely used in cosmetics as an antioxidant and skin-lightening agent to inhibit tyrosinase activity and reduce melanin production. In pharmaceutical and nutraceutical fields, it serves as a vitamin C supplement and antioxidant component.
Technical Specifications:
Assay (HPLC): ≥98.0%
Appearance: White to off-white crystalline powder
Solubility: Freely soluble in water, slightly soluble in ethanol
Loss on drying: 10.0%–12.0% (dihydrate)
Heavy metals (as Pb): ≤10ppm
