Description
Potassium dihydrogen phosphate ROTI®METIC 99,99 % (4N) is a high-purity inorganic salt with CAS number 7778-77-0 and empirical formula KH₂PO₄. The compound has a molar mass of 136,09 g/mol and a density of 2,34 g/cm³, providing well-defined physicochemical parameters for quantitative laboratory use. The ROTI®METIC 99,99 % (4N) grade from manufacturer Carl ROTH targets applications that require tightly controlled impurity profiles in phosphate chemistry. Typical uses include pH-buffer systems, calibration media and research formulations where potassium and phosphate content must remain consistent. Identification is completed by EG number 231-913-4. Clear molar mass and density values support accurate weighing and solution preparation, helping laboratories maintain reproducible results across analytical, biochemical and materials-oriented workflows that rely on high-purity monobasic potassium phosphate.

Questions about Potassium dihydrogen phosphate, ROTI®METIC 99,99 % (4N), 5 g, HDPE
What is this article?
Potassium dihydrogen phosphate, ROTI®METIC 99,99 % (4N), 5 g, HDPE 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.
