Description

Potassium iodate (CAS 7758-05-6 ), commonly referenced by its formula KIO3, is an inorganic iodine salt used as an oxidizing and iodizing agent across food, pharmaceutical, and industrial applications. Its controlled release of iodine makes it a preferred source for fortification programs and oxidative processing where precision dosing matters. In food manufacturing, KIO3 is the active ingredient in salt iodization programs. This material meets WHO-aligned fortification standards for iodine deficiency prevention at the population level. Flour treatment plants use it as a dough conditioner and bleaching agent to improve gluten structure. It is also utilized to enhance crumb whiteness in commercial bread production. Pharmaceutical manufacturers incorporate it into iodine supplement formulations and as a thyroid-blocking agent in radiation emergency preparedness. In water treatment, it functions as a disinfection aid and oxidant for controlling microbial load in municipal and industrial systems. The product is supplied as a white crystalline powder or fine granules. Standard grades include food-grade ( FCC ), USP , and technical-grade material. Food and pharma grades are subject to strict purity thresholds, which are typically 99% or higher for most industrial uses. Packaging ranges from small drums to bulk quantities, with moisture-controlled storage requirements. Buyers should factor these specific environmental needs into their logistics planning and warehouse management. Contact us for supply of Potassium iodate Request Quote
