Description
di-Sodium hydrogen citrate 1,5-hydrate is a crystalline citrate salt of minimum 99 % purity, supplied for laboratory and synthesis work. Its empirical formula is C₆H₆Na₂O₇ · 1,5 H₂O, with a molar mass of 263,11 g/mol and CAS number 6132-05-4 (EG nr. 205-623-3). The material is offered as a free-flowing crystalline solid that dissolves readily in aqueous systems, making it suitable for buffer preparation, pH adjustment and general analytical chemistry. The sesquihydrate form supports consistent weighing and formulation in media, reagents and process chemistry. Laboratories value the defined assay and clear identity data for documentation and method transfer. Use the product according to standard laboratory practice for citrate salts in research, quality control and preparative applications where a high-purity disodium hydrogen citrate hydrate is required.
This article is part of Inorganic salts, in Inorganic chemicals.

Questions about di-Sodium hydrogen citrate 1,5-hydrate, min. 99 %, cryst., 250 g, plastic
What is this article?
di-Sodium hydrogen citrate 1,5-hydrate, min. 99 %, cryst., 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.
