Description
Potassium chloride, min. 99 %, is an inorganic salt in pharmacopoeia quality conforming to Ph.Eur., USP and BP requirements. With CAS number 7447-40-7 and empirical formula KCl, it has a molar mass of 74,56 g/mol, a density of 1,98 g/cm³ and a boiling point of 1413 °C. This high-purity chloride is a standard laboratory reagent for buffer systems, electrolyte solutions, calibration media and general inorganic preparation where a defined potassium source is essential. The product is Identity data including EG nr. 231-211-8 support straightforward registration in quality systems. Typical uses include physiological and analytical buffer formulation, conductivity and ion standards, and pharmaceutical or life-science laboratories that specify pharmacopoeia-grade potassium chloride with a minimum assay of 99 %. The kilogram pack size offers efficient handling for continuous laboratory demand.

Questions about Potassium chloride, min. 99 %, Ph.Eur., USP, BP, 500 g, plastic
What is this article?
Potassium chloride, min. 99 %, Ph.Eur., USP, 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.
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.
