Description
Sodium iodide is an inorganic alkali metal salt offered at min. 99 % purity in Ph.Eur. quality, with empirical formula NaI and CAS number 7681-82-5. The compound has a molar mass of 149,89 g/mol, a density of 3,5 g/cm³ and a boiling point of 1304 °C, providing a dense, well-characterised iodide source for pharmaceutical and laboratory applications. Eur. grade is intended for uses that require pharmacopoeia-aligned sodium iodide with documented purity. Typical applications include preparation of iodide solutions, analytical chemistry, and research or formulation work where a high-purity NaI salt is specified. The material is identified under EG number 231-679-3 and carries UN number 3077 for transport classification. Laboratories and production environments rely on the min. 99 %. Ph.Eur. specification when consistent composition, reliable weighing behaviour and clear identity data are essential for reproducible results in inorganic and pharmaceutical chemistry.

Questions about Sodium iodide, min. 99 %, Ph.Eur., 250 g, plastic
What is this article?
Sodium iodide, min. 99 %, Ph.Eur., 250 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
Which category should I open next?
The category is Inorganic chemicals. The sub-category is Inorganic salts. The catalogue is Lab chemicals.
Shelves beside this one are Metals, elements & oxides and Nanomaterials & quantum dots.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
