Description
di-Potassium hydrogen phosphate ROTI®METIC 99.99 % (4N), anhydrous, is a high-purity inorganic phosphate salt with the empirical formula K₂HPO₄ and CAS number 7758-11-4. The anhydrous material has a molar mass of 174,18 g/mol and a density of 2,44 g/cm³, providing a well-specified reagent for laboratory buffer and salt preparation. Stated purity of 99.99 % (4N) suits analytical and research settings that require controlled potassium phosphate feedstock. The product is supplied in a 25 g pack, a convenient size for buffer stock solutions, method development and small-batch inorganic work. di-Potassium hydrogen phosphate is widely employed as a buffering component and potassium/phosphate source in chemical, biochemical and analytical laboratories. This ROTI®METIC grade from manufacturer Carl ROTH offers a defined anhydrous profile under EG number 231-834-5 for professional use. Laboratories specifying high-purity K₂HPO₄ for reproducible buffer systems, calibration mixtures or specialised salt chemistry will find this 25 g anhydrous unit clearly aligned with those requirements.

Questions about di-Potassium hydrogen phosphate, ROTI®METIC 99.99 % (4N), anhydrous, 25 g
What is this article?
di-Potassium hydrogen phosphate, ROTI®METIC 99.99 % (4N), anhydrous, 25 g 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.
