Description
di-Sodium hydrogen phosphate is a high-purity inorganic salt supplied at min. 99 % as p.a., ISO grade material for analytical laboratory work. It carries CAS number 10039-32-4 and the empirical formula Na₂HPO₄ · 12 H₂O, with a molar mass of 358,14 g/mol and a density of 1,52 g/cm³. The boiling point is reported in the range 30 to 40 °C. This dodecahydrate form is widely used where defined phosphate content and reliable assay quality are required in inorganic salt preparations and wet-chemical analysis. Offered in a practical, the product supports routine weighing, solution preparation and buffer-related workflows in research and quality-control laboratories. The grade designation p.a., ISO underlines its suitability for precise analytical applications among salts for analysis. Physical data including molar mass and density help method development and stoichiometric calculations. This reagent is available from manufacturer Carl ROTH as a clearly specified laboratory chemical, enabling consistent batch handling without unnecessary formulation complexity. EG number 600-088-6 completes the identity profile for documentation and inventory systems.

Questions about di-Sodium hydrogen phosphate, min. 99 %, p.a., ISO, 500 g, plastic
What is this article?
di-Sodium hydrogen phosphate, min. 99 %, p.a., ISO, 500 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.
