A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Calcium ascorbate (CAS 5743-28-2) is the calcium salt of L-ascorbic acid (vitamin C). It is used as a food-grade antioxidant and as a source of ascorbate and calcium for food fortification and supplement manufacturing.
Frequently Asked Questions
What is calcium ascorbate made of?
Calcium ascorbate (CAS 5743-28-2, C12H18CaO14) is the calcium salt of L-ascorbic acid (vitamin C). It is manufactured by reacting ascorbic acid with a calcium source, yielding a buffered ascorbate that also supplies calcium.
Is calcium ascorbate actually a source of calcium?
Yes — the molecule is the calcium salt of ascorbic acid, so each unit carries bound calcium alongside the ascorbate. It is used in food fortification and supplement manufacturing as a source of both ascorbate and calcium.
What is calcium ascorbate used for in manufacturing?
It functions as a food-grade antioxidant in food and beverage processing and as a raw material for vitamin-C and calcium fortification in foods and dietary supplements. This grade is supplied USP/FCC, 20-mesh granular, and Kosher.
What does 20 mesh granular mean for this grade?
20 mesh describes the particle size — granular material that passes a 20-mesh screen, coarser and more free-flowing than fine powder. Granular grades reduce dusting and are often preferred for dry blending and direct-compression formats.
Does RawSource supply calcium ascorbate in bulk with CoA and SDS?
Yes. RawSource distributes USP/FCC calcium ascorbate in bulk and provides a Certificate of Analysis and Safety Data Sheet with shipments. Request Kosher and USP/FCC documentation against CAS 5743-28-2 when you submit an RFQ.
