Calcium Iodate CAS 7789-80-2

What Calcium Iodate Is

Calcium iodate is the calcium salt of iodic acid, a white to off-white, odorless crystalline powder that is slightly soluble in water and insoluble in alcohol. Commercial feed material is usually the monohydrate, Ca(IO₃)₂·H₂O, while the anhydrous formula Ca(IO₃)₂ carries molecular weight 389.88. The iodate form is non-hygroscopic and chemically stable, so feed producers choose it over potassium iodide. As an oxidizing salt it is kept dry and separated from reducing agents and strong acids. UATChem supplies feed and food grade lots with controlled heavy metals and a defined iodine content.

A Stable Iodine Source for Feed and Food

• Animal feed. The iodine source in vitamin and mineral premixes, compound feed and mineral blocks to prevent iodine deficiency and support thyroid function; the stable iodate keeps iodine through storage and contact with copper and iron in a premix.
• Baking and food. A fast-acting oxidizing dough conditioner that strengthens flour and improves baking performance, and an iodine source for food fortification at food grade.
• Pharmaceutical and other uses. Used in mouthwash and iodine preparations and as a mild oxidant in fine chemical and reagent applications.

Typical Specifications

Values are typical for feed grade monohydrate; anhydrous and food or pharmacopoeia grades carry different iodine and impurity limits and are confirmed per order.

Packaging, Documents and Ordering

• Packed in 25 kg plastic-lined woven bags, paperboard or fiber drums and in 1000 kg FIBC bags; keep material sealed, dry, out of light and away from reducing agents and strong acids, with transport classification shown on the SDS.
• Every lot carries a COA with iodine and Ca(IO₃)₂ content, moisture, fineness and lead and arsenic limits, together with SDS; feed and food grade compliance documents can be discussed at inquiry and samples are supported.
• Calcium iodate is usually blended into compound mineral premixes alongside other trace mineral sources such as Chelated Magnesium Amino Acid CAS 14783-68-7. For a quote, send the grade (feed or food), iodine target, quantity, packing and destination port.

FAQ

Q: Why use calcium iodate instead of potassium iodide in feed?

A: It is non-hygroscopic and oxidation resistant, so iodine survives storage and trace metal contact, unlike potassium iodide.

Q: What iodine content does feed grade calcium iodate have?

A: Feed grade monohydrate runs about 61.8 to 62.8% iodine as off-white powder per HG 2418, with heavy metal limits and COA.

Q: Is calcium iodate only used in animal feed?

A: Feed is the main use; food grade serves as a dough conditioner and iodine source, and it also appears in mouthwash.
