Description
Potassium hydrogen carbonate is an inorganic salt of high pharmacopoeia quality, supplied at a minimum purity of 99 % according to Ph.Eur. With CAS number 298-14-6 and empirical formula KHCO₃, it has a molar mass of 100,12 g/mol and a density of 2,17 g/cm³. This crystalline potassium hydrogen carbonate is widely used in analytical chemistry, buffer preparation, pharmaceutical formulation work, and general laboratory synthesis where a reliable bicarbonate source is required. The material is offered in a practical, suited to routine bench use and controlled dispensing. Produced by manufacturer Carl ROTH, it meets established pharmacopoeia specifications for laboratories that need consistent quality and clear identity data. Typical applications include pH adjustment, preparation of carbonate/bicarbonate systems, and supporting inorganic salt workflows in research and quality-control environments. Its defined physical constants and Ph.Eur. grade support reproducible results across method development and routine analysis.

Questions about Potassium hydrogen carbonate, min. 99 %, Ph.Eur., 500 g, plastic
What is this article?
Potassium hydrogen carbonate, min. 99 %, Ph.Eur., 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.
