Potassium iodate CAS#7758-05-6

Potassium iodate is an iodine-rich salt with the formula KIO3. In hot and humid climates, iodine vapor is hydrolyzed due to the hygroscopicity of potassium iodide. Compared to potassium iodide, potassium iodate is more stable and has a longer shelf life. It is a potent blocker of radioactive iodine uptake by the thyroid gland.Colorless monoclinic crystal or white crystalline powder. Odorless. Soluble in water, dilute acid, ethylenediamine, ethanolamine, and potassium iodide aqueous solutions; slightly soluble in liquid sulfur dioxide; insoluble in alcohols and ammonia.Colorless crystals or white powder; monoclinic structure; density 3.90 g/cm3; stable at ordinary temperatures; melts at 560°C with partial decompo-sition, releasing oxygen; moderately soluble in cold water; 4.74 g/100mL at 0°C; greater solubility in boiling water 32.3 g/100mL at 100°C; soluble in potassium iodide solution; insoluble in alcohol and liquid ammonia.

Product Application of Potassium iodate CAS#7758-05-6

Potassium iodate is a fairly strong oxidizing agent that may be used in the assay of a number of pharmaceutical substances, for instance : benzalkonium chloride, cetrimide, hydralazine hydrochloride, potassium iodide, phenylhydrazine hydrochloride, semicarbazide hydrochloride and the like. Under appropriate experimental parameters the iodate reacts quantitatively with both iodides and iodine. It is, however, interesting to observe here that the iodate titrations may be carried out effectively in the presence of saturated organic acids, alcohol and a host of other organic substances.
The oxidation-reduction methods with potassium iodate invariably based on the formation of iodine monochloride (ICl) in a medium of strong hydrochloric acid solution.
