Description
Potassium iodide is an inorganic salt of high assay, specified at minimum 99 % and meeting Ph. Eur., BP and USP pharmacopoeia quality requirements. It has the empirical formula KI, CAS number 7681-11-0 and EG number 231-659-4, with a molar mass of 166,01 g/mol, a density of 3,12 g/cm³ and a boiling point of 1325 °C. These well-defined physical data support accurate weighing, solution preparation and documentation in regulated and research laboratories. Pharmacopoeia alignment facilitates use where monographs and quality systems require Ph. Eur., BP or USP-grade reagents. Clear identity, high minimum assay and stable solid form make this potassium iodide a practical choice for stock solutions, reference work and routine synthesis or titration protocols that depend on consistent iodide content.

Questions about Potassium iodide, min. 99 %, Ph. Eur., BP, USP, 100 g, glass
What is this article?
Potassium iodide, min. 99 %, Ph. Eur., BP, USP, 100 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.
