Products Description
Ascorbic Acid, also known as L-Ascorbic Acid or Vitamin C, has CAS 50-81-7, molecular formula C₆H₈O₆ and molecular weight 176.12. It appears as white or slightly yellow crystalline powder or granules, with a tart taste. It dissolves readily in water and methanol, slightly soluble in ethanol. It is sensitive to heat, light and oxygen, which will trigger gradual degradation. We supply food, feed and pharma grades with high purity. It is non-dangerous goods for transportation, normally packed in 25kg cardboard drums or paper bags. It is exported to food factories, feed plants and pharmaceutical manufacturers for antioxidant and nutritional enhancement purposes.
