Food Grade Ascorbic Acid With CAS No. 50-81-7

Food Grade Ascorbic acid with CAS No. 50-81-7 Product Overview Vitamin C, also known as ascorbic acid, is an acidic polyhydroxy compound containing 6 carbon atoms and has a molecular formula of C6H8O6 and a molecular weight of 176.1. Natural ascorbic acid has two kinds of L-type and D-type, and the latter has no biological activity. Vitamin C is a colorless, odorless flake crystal which is easily soluble in water and insoluble in organic solvents. It is stable in acidic environment, when met oxygen, heat, light and alkaline substances in the air, particularly oxidases and trace amounts of copper, iron and other metal ions, it will be easily broken by oxidative. Oxygenases are generally found in vegetables, so it is lost during storage more or less. However, bioflavonoids contained in certain fruits can protect their stability. It is a white solid, but impure samples can appear yellowish.  Physical Properties CAS No. : 50-81-7MF: C6H8O6MW: 176.12EINECS: 200-066-2 Melting Point: 190-194 °C (dec.)Specific Rotation: 20.5 º (c=10,H2O)Density: 1.65 g/cm3FEMA 2109 | ASCORBIC ACIDRefractive Index: 21 ° (C=10, H2O)Storage:  0-6°CSolubility: H2O: 50 mg/mL at 20 °C, clear, nearly colorlessForm: powderAcidity Coefficient: (pKa) 4.04, 11.7(at 25℃)Color: white to slightly yellowPH: 1.0 - 2.5 (25℃, 176g/L in water)Solubility in water: 333 g/L (20 ºC) Function 1) It can be used in food additive.
