Description
Potassium hydrogen sulphate is an inorganic acid salt offered at min. 98 % purity in extra pure quality, with empirical formula KHSO₄, CAS number 7646-93-7 and molar mass 136,17 g/mol. It has a density of 2,32 g/cm³ and carries EG nr. 231-594-1, supporting clear identification in laboratory documentation. In the laboratory it is used as a (Lewis) acid and synthesis reagent, for example in organic and inorganic preparations, pH adjustment of selected media, fusion or dehydration steps, and other workflows that require a defined potassium hydrogen sulphate grade. This material comes from manufacturer Carl ROTH within its extra pure chemicals portfolio. Documented purity, molar mass and density help analysts and process chemists specify the reagent consistently across methods. suits research, teaching and quality-control environments that need a reliable KHSO₄ source without oversized bulk packaging.

Questions about Potassium hydrogen sulphate, min. 98 %, extra pure, 500 g, plastic
What is this article?
Potassium hydrogen sulphate, min. 98 %, extra pure, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
