English description(英文原文,共 1284 字符)
Product Name:Sodium ascorbate
English Name:Sodium ascorbate
CAS No.:134-03-2
Aliases:Sodium L-ascorbate, Vitamin C sodium, L-Ascorbic acid sodium salt, L-(+)-Sodium threo-2,3,4,5,6-pentahydroxy-2-hexenoic acid-4-lactone
Molecular Formula:C6H7NaO6
Physical Properties:White to slightly yellow crystalline powder, odorless, with a salty taste. Freely soluble in water (620 g/L at 20 °C), aqueous solution is neutral to slightly alkaline, insoluble in ethanol, ether and other organic solvents. Melting point 219-221 °C (decomposition), specific rotation +104° (C=1, H2O, 25 °C). It has reducing properties, stable in dry air, while aqueous solutions are gradually oxidized and discolored when exposed to air and light.
Uses:This product is the sodium salt of L-ascorbic acid, with physiological effects equivalent to L-ascorbic acid, but more soluble in water and free of acidic taste. It is widely used as an antioxidant, nutritional fortifier and color-protecting agent in food, pharmaceutical and cosmetic fields. The application scope and dosage are the same as those of L-ascorbic acid.
