Description
Potassium chloride, min. 99,5 %, p.a., ACS, ISO is an analytical-grade inorganic salt with CAS number 7447-40-7 and EG number 231-211-8. Its empirical formula is KCl, with a molar mass of 74,56 g/mol, a density of 1,98 g/cm³, and a boiling point of 1413 °C. The minimum purity of 99,5 % together with p.a., ACS, and ISO designations makes this grade appropriate for quantitative analysis, electrolyte standards, and high-purity reagent preparation. Potassium chloride is highly soluble in water and remains a staple salt for ion chromatography, flame photometry, and physiological solution work. Available from manufacturer Carl ROTH in this ACS/ISO p.a. quality, it provides a reliable bulk source for analytical and research laboratories that require tight assay control and consistent physical properties. The defined crystalline salt enables accurate preparation of stock solutions and reference media across inorganic and biochemical workflows.

Questions about Potassium chloride, min. 99,5 %, p.a., ACS, ISO, 10 g, glass
What is this article?
Potassium chloride, min. 99,5 %, p.a., ACS, ISO, 10 g, glass 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.
Shelves beside this one are Metals, elements & oxides and Nanomaterials & quantum dots.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
