Description
Sodium selenite is an inorganic salt supplied at min. 99 % purity in p.a. quality for analytical laboratory use. It is identified by CAS number 10102-18-8, EG nr. 233-267-9 and the empirical formula Na₂SeO₃, with a molar mass of 172,94 g/mol and a density of 3,1 g/cm³. This grade is intended for salts-for-analysis workflows where a defined selenite source is required in inorganic chemistry, method development or related experimental work. The material is Sodium selenite from manufacturer Carl ROTH is listed among inorganic salts for analysis (p.a.) and supports laboratories that specify high-purity reagents with transparent identity data. Physical constants such as molar mass and density assist stoichiometry, solution making and documentation. UN number 2630 is associated with the substance in the manufacturer data. Overall, a. option for controlled laboratory handling of sodium selenite in analytical settings.
This article belongs on Inorganic salts, in Inorganic chemicals.

Questions about Sodium selenite, min. 99 %, p.a., 100 g, plastic
What is this article?
Sodium selenite, min. 99 %, p.a., 100 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.
