Iodine [7553-56-2]
DEFINITION Iodine contains NLT 99.8% and NMT 100.5% of I.
IDENTIFICATION
• A. Solutions (1 in 1000) in chloroform and in carbon disulfide have a violet color.
• B.
Analysis: To a saturated solution add starch-potassium iodide TS.
Acceptance criteria: A blue color is produced. When the mixture is boiled, the color vanishes but reappears as the mixture cools, unless it has been subjected to prolonged boiling.
ASSAY
• PROCEDURE
Sample: 500 mg of powdered Iodine
Analysis: Place the Sample in a tared, glass-stoppered flask insert the stopper, and add 1 g of potassium iodide dissolved in 5 mL of water. Dilute with water to 50 mL, add 1mL of 3 N hydrochloric acid, and titrate with 0.1 N sodium thiosulfate VS, adding 3 mL of star ch TS as the endpoint is approached. Each mL of 0.1 N sodium thiosulfate is equivalent to 12.69 mg of Iodine (I).
Acceptance criteria: 99.8%~100.5%
IMPURITIES
LIMIT OF CHLORIDE OR BROMIDE
• LIMIT OF CHLORIDE OR BROMIDE
Sample solution: Triturate 250 mg of finely powdered Iodine with 10 mL of water, and filter the solution.
Analysis: To the Sample solution add, dropwise, sulfurous acid (free from chloride), previously diluted with several volumes of water, until the iodine color just disappears. Add 5 mL of 6 N ammonium hydroxide, followed by 5 mL of silver nitrate TS in small portions. Filter, and acidify the filtrate with nitric acid.
Acceptance criteria: The resulting liquid is not more turbid than a control made with the same quantities of the same reagents to which 0.10 mL of 0.020 N hydrochloric acid has been added, the sulfurous acid being omitted (0.028% as chloride).
• LIMIT OF NONVOLATILE RESIDUE
Analysis: Place 5.0 g in a tared por celain dish, heat on a steam bath until the iodine has been driven off, and dry at 105° for 1 h.
Acceptance criteria: NMT 0.05% of the residue remains.
ADDITIONAL REQUIREMENTS
• PACKAGING AND STORAGE: Preserve in tight containers.

Iodine (CAS: 12190-71-5), mainly used to make iodide, used to make pesticides, feed additives, dyes, iodine, test paper, drugs, etc. used to prepare equivalent solvents, measure iodine value, and calibrate the concentration of sodium thiosulfate solution. The solution can be used as a disinfectant, photographic plate preparation for iodine and thinning solution.
One of the most important uses of Iodine is in the treatment of hypothyroidism, a conditionin which the thyroid gland is deficient in iodine. Iodine deficiency may lead to the formationof a goiter, wherein the gland that surrounds the windpipe in the neck becomes enlarged. There are other causes of goiter, including cancer of the thyroid gland. Some food grown in iodine-deficient soils do not contain adequate iodine forour diets. This is why Iodine was added to table salt (about 0.01% potassium iodide) decadesago, specifically for people who live in regions with iodine-poor soils. In industry, Iodine is used for dyes, antiseptics, germicides, X-ray contrast medium, foodand feed additives, pharmaceuticals, medical soaps, and photographic film emulsions and as alaboratory catalyst to either speed up or slow down chemical reactions. Iodine is also used as a test for starch. When placed on starch (a potato for example), iodineturns the starch a dark blue color. Silver iodide is used in the manufacture of photographicfilm and paper. It is also used to “seed” clouds because of its ability to form a large numberof crystals that act as nuclei upon which moisture in the clouds condenses, forming raindropsthat may result in rain.
1. Used in the manufacture of iodine. 2. Used as make pesticide, feed additives, dye, iodine, test, and medications. 3. Used to make equivalent solvent, determine iodine value, 4. Contentanded calibration of sodium solution concentration. 5. Solution can be disinfectant, photoengraving for good fittings and thinning liquid preparation.
