Description
Potassium iodide is an inorganic salt of minimum 99,5 % purity, graded p.a. and ISO, with CAS number 7681-11-0 and empirical formula KI. It has a molar mass of 166,01 g/mol, density of 3,12 g/cm³ and boiling point of 1325 °C, providing stable, well-characterised material for analytical and preparative work. Potassium iodide from manufacturer Carl ROTH is commonly applied in salts for analysis (p.a.), titration media, halogen-exchange reactions and spectroscopic sample work where high assay and ISO-aligned specification matter. The defined EG nr. 231-659-4 supports regulatory and inventory documentation. Its solid form and analytical grade make it suitable for preparing standard solutions and for use as a reliable iodide source in inorganic and analytical protocols across chemical laboratories.

Questions about Potassium iodide, min. 99.5 %, p.a., ISO, 250 g, glass
What is this article?
Potassium iodide, min. 99.5 %, p.a., ISO, 250 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.
