Sodium iodide is used to treat iodine deficiency

21/01/2014 13:56

Sodium iodide is a white, crystalline salt with the chemical formula NaI, and is used in radiation detection, treatment of iodine deficiency, and as a reactant in the Finkelstein reaction. It is manufactured from the reaction between iodine and sodium hydroxide. It is stable under normal temperatures and pressures, the Water Solubility is 184 g/100 mL. It is an iodide salt that is formed into an injectable medicine, and the CAS Registry Number is 7681-82-5.

It has three important uses: Food supplement, Organic synthesis, Radiation physics and medicine.

As a Food supplement, it is commonly used to treat and prevent iodine deficiency. Iodized table salt contains one part sodium or potassium iodide to 100,000 parts of sodium chloride.

As a Organic synthesis,Sodium iodide(cas no: 7681-82-5) is used in the Finkelstein reaction, for conversion of an alkyl chloride into an alkyl iodide. This method relies on the insolubility of sodium chloride in acetone to drive the reaction: R-Cl + NaI → R-I + NaCl

As a medicine, Sodium iodide is used to treat or prevent iodine deficiency caused by poor nutrition or poor absorption by the body. It may also be used to treat a thyroid disorder.

Sodium iodide activated with thallium, NaI(Tl), when subjected to ionizing radiation, emits photons and is used in scintillation detectors, traditionally in nuclear medicine, geophysics, nuclear physics, and environmental measurements. NaI(Tl) is the most widely used scintillation material.

The crystals are usually coupled with a photomultiplier tube, in a hermetically sealed assembly, as sodium iodide is hygroscopic. Fine-tuning of some parameters can be achieved by varying the conditions of the crystal growth. Crystals with a higher level of doping are used in X-ray detectors with high spectrometric quality. Sodium iodide can be used both as single crystals and as polycrystals for this purpose.

The body needs iodine for normal growth and health. For patients who are unable to get enough iodine in their regular diet or who have a need for more iodine, sodium iodide may be necessary. Iodine is needed so that your thyroid gland can function properly.

Iodine deficiency in the United States is rare because iodine is added to table salt. Most people get enough salt from the foods they eat, without adding salt to their meals. Iodine deficiency is a problem in other areas of the world.

Lack of iodine may lead to thyroid problems, mental problems, hearing loss, and goiter.Injectable sodium iodide is administered only by or under the supervision of a health care professional. Some multivitamin/mineral preparations that contain sodium iodide are available without your health care professional's prescription.
