Request SDS →Ascorbic acid (vitamin C) is a water-soluble vitamin and strong reducing agent used chiefly as an antioxidant and preservative. In food and beverage processing it protects against oxidation, fixes color in cured meats, and conditions bread dough, and as a dietary supplement and fortificant it restores nutritional value. In personal care it functions as an antioxidant and pH adjuster, and in analytical chemistry it serves as a reducing agent.

Frequently Asked Questions
What is ascorbic acid used for?
Ascorbic acid (vitamin C, CAS 50-81-7, C6H8O6) is used industrially as an antioxidant and reducing agent, an acidity regulator and preservative in food and beverage processing, and as a raw material in dietary, cosmetic, and chemical formulations. Specify your grade requirement (e.g., food, cosmetic, technical).
Is ascorbic acid the same thing as vitamin C?
Yes. Ascorbic acid is the chemical name for vitamin C (L-ascorbic acid), CAS 50-81-7. We supply it as a bulk raw material; grade and specification are confirmed on the CoA.
Is ascorbic acid water soluble?
Yes. Ascorbic acid is highly water-soluble, which is why it is used as an antioxidant and acidity regulator in aqueous food, beverage, and personal-care systems. Solubility and assay are stated on the product specification.
What is the CAS number and formula for ascorbic acid?
Ascorbic acid has CAS 50-81-7 and molecular formula C6H8O6. Each lot ships with a CoA stating assay and grade, along with an SDS.
How is bulk ascorbic acid supplied and quoted?
We supply ascorbic acid in bulk to food, beverage, supplement, and cosmetic manufacturers. Request a quote with your target volume and required grade (food/cosmetic/technical) for pricing, lead time, CoA, and SDS rather than a list price.
What is the REACH and TSCA regulatory status of Ascorbic Acid (Vitamin C)?
Ascorbic Acid (Vitamin C) (CAS 50-81-7) is listed as Active on the U.S. EPA TSCA Inventory; its REACH registration status is not determined from the public ECHA registry.
