Sodium Iodide Anhydrous Dihydrate
CAS Number: 7681-82-5 Anhydrous, 13517-06-1 Dihydrate
Molecular Formula: NaI
Molecular Weight: 149.89
Sodium Iodide Anhydrous Dihydrate
Sodium Iodide USP Grade Specifications
NaI -- 149.89 -- CAS 7681-82-5
Sodium Iodide contains not less than 99.0 percent and not more than 101.5 percent of NaI, calculated on the anhydrous basis.
Identification: A solution (1 in 20) responds to the tests for Sodium and for Iodide.
Alkalinity: Dissolve 1.0 g in 10 mL of water, and add 0.15 mL of 0.10 N sulfuric acid: no red color is produced by the addition of 1 drop of PhPh TS.
Water: not more than 2.0%.
Iodate: It meets the requirements of the test for Iodate under Potassium Iodide, 100 mg of Sodium Iodide being used in the control.
Thiosulfate and barium: It meets the requirements of the test for Thiosulfate and barium under Potassium Iodide.
Potassium: A solution of 1.0 g in 2 mL of water yields no precipitate with 1.0 mL of sodium bitartrate.
Heavy metals: Dissolve 2.0 g in 25 mL of water: the limit is 0.001%.
Limit of nitrate, nitrite, and ammonia: Add 5 mL of 1 N sodium hydroxide and about 200 mg of aluminum wire to a solution of 1.0 g of Sodium Iodide in 5 mL of water, contained in a test tube of about 40-mL capacity. Insert a pledget of purified cotton in the upper portion of the test tube, and place a piece of moistened red litmus paper over the mouth of the tube. Heat in a steam bath for 15 minutes: no blue coloration of the paper is discernible.
