Sodium iodide Specification

The Sodium iodide, with the CAS registry number 7681-82-5, is also known as Sodium monoiodide. It belongs to the product categories of Inorganics; Analytical Reagents for General Use; Essential Chemicals; Reagent Plus; Routine Reagents; Inorganic Salts; Synthetic Reagents; Pharmacopoeia (USP); Pharmacopoeial Inorganics; Crystal Grade Inorganics; Salts; Sodium Salts; Sodium Metal and Ceramic Science; Metal and Ceramic Science; ACS Grade Synthetic Reagents; Chemical Synthesis; Crystal Grade Inorganics; Inorganic Salts; Materials Science. Its EINECS number is 231-679-3. This chemical's molecular formula is NaI and molecular weight is 149.89. What's more, its systematic name is Sodium iodide. Its classification codes are: (1)Human Data; (2)Reproductive Effect; (3)Skin / Eye Irritant; (4)Supplement [iodine]. This chemical should be sealed and stored in a cool and dry place. Moreover, it should be protected from light. It is used in radiation detection, treatment of iodine deficiency, and as a reactant in the Finkelstein reaction. Sodium iodide is manufactured from the reaction between iodine and sodium hydroxide.

When you are using this chemical, please be cautious about it as the following:
This chemical is irritating to eyes, respiratory system and skin. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice.

You can still convert the following datas into molecular structure:
(1)SMILES: [Na+].[I-]
(2)Std. InChI: InChI=1S/HI.Na/h1H;/q;+1/p-1
