Description
di-Sodium hydrogen phosphate dihydrate is an analytical-grade inorganic salt with a minimum purity of 99,0 % p.a. for laboratory use. Registered under CAS number 10028-24-7 and empirical formula Na₂HPO₄ · 2 H₂O, it has a molar mass of 177,99 g/mol and a density of 2,1 g/cm³. This dibasic sodium phosphate hydrate is a standard component of phosphate buffer systems, pH adjustment reagents, and analytical preparations in chemistry and life-science laboratories. a. quality supports precise buffer formulation and quantitative work where consistent salt composition is required. It is suitable for preparing phosphate standards, culture media supplements, and general inorganic reagent solutions. The product is associated with EG number 231-448-7. Laboratories rely on this dihydrate when a defined, high-assay sodium hydrogen phosphate source is needed for analytical chemistry, buffer chemistry, and routine inorganic salt applications.

Questions about di-Sodium hydrogen phosphate dihydrate, min. 99,0 %, p.a., 500 g, plastic
What is this article?
di-Sodium hydrogen phosphate dihydrate, min. 99,0 %, p.a., 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.
