Product Description of Iodine CAS#7553-56-2
Iodine can be naturally sourced from sea-weed. The American Food and Drug Administration has classified this element as a GRAS (Generally Recognized As Safe) ingredient. It ranks as an indispensable trace-element for human beings and numerous other living creatures. People have acknowledged its ability to avoid goitre ever since 1819, hence it is routinely incorporated into iodized table-salt. Commercial baking industries also employ it as an oxidising agent for dough treatment.
Industrial-grade iodine is mostly recovered from natural brine and oil-well saline water. Chlorine is utilised to oxidise iodide ions, and flowing air strips the generated elemental iodine out of the liquid mixture. The extracted iodine gets dissolved once more and reduced into hydriodic acid with sulphur-dioxide. Another chlorination procedure precipitates elemental iodine, and concentrated sulphuric-acid processing completes its purification. Iodine is the heaviest necessary nutrient for the majority of living organisms, whereas several bacterial species adopt tungsten to carry out comparable biological functions.

Product Applications of Iodine CAS#7553-56-2
Iodine is primarily adopted for manufacturing iodide compounds, agro-chemicals, animal-feed supplements, colourants, iodine tincture, test strips, medicines and diverse chemical goods. High-purity iodine also acts as raw material and lab-grade reagent within the electronics-manufacturing sector.
It takes part in titration and colour-based detection work for analytical-chemistry experiments. Both organic and inorganic iodide substances are synthesised relying on this essential feedstock. Within the health-care industry, plenty of iodine-containing formulations, bactericides, sanitizers, odour-removing agents, pain-relieving supplies and radioactive-poison antidotes are produced from it.
For industrial-level production, this element assists the preparation of dyestuffs, smoke-suppressing additives, photographic emulsions and antibacterial additives applied to cutting-oil emulsions.
