Description
Potassium dihydrogen phosphate is an inorganic phosphate salt of pharmacopoeia quality with a minimum assay of 98 %, conforming to Ph.Eur. and BP. It carries CAS number 7778-77-0, EG number 231-913-4 and the empirical formula KH₂PO₄, with a molar mass of 136,09 g/mol and a density of 2,34 g/cm³. The material belongs to the salts in pharmacopoeia quality range and supports analytical, pharmaceutical and research applications that call for a well-characterised KH₂PO₄ source. Its defined molar mass and density facilitate accurate weighing and solution preparation in aqueous systems. Use according to laboratory good practice and the accompanying safety documentation when handling the solid reagent.

Questions about Potassium dihydrogen phosphate, min. 98 %, Ph.Eur., BP, 500 g, plastic
What is this article?
Potassium dihydrogen phosphate, min. 98 %, Ph.Eur., BP, 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.
Which category should I open next?
The category is Inorganic chemicals. The sub-category is Inorganic salts. The catalogue is Lab chemicals.
