Description
Sodium iodide is a high-purity inorganic salt supplied at min. 99,5 % for analytical work, meeting p.a. and ACS requirements. With the empirical formula NaI, CAS number 7681-82-5 and EG nr. 231-679-3, it offers a molar mass of 149,89 g/mol and a density of 3,5 g/cm³. The boiling point is 1304 °C, supporting use under demanding thermal conditions in the laboratory. This grade is intended for quantitative analysis, reagent preparation and general inorganic chemistry applications where consistent assay and low impurity levels matter. Sodium iodide from manufacturer Carl ROTH fits salts-for-analysis workflows in research, quality control and teaching laboratories. Its defined physical data and analytical specification help ensure reproducible results in titrations, spectroscopic sample preparation and synthesis steps that rely on a reliable iodide source.

Questions about Sodium iodide, min. 99.5 %, p.a., ACS, 250 g, plastic
What is this article?
Sodium iodide, min. 99.5 %, p.a., ACS, 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.
