Description
Potassium iodide solution, saturated is a pharmacopoeia-quality laboratory reagent corresponding to Reag. Ph. Eur., Chapter 4.1.1, 1070504. It is based on potassium iodide, empirical formula KI, with a molar mass of 166,00 g/mol. The saturated solution is intended for analytical work that requires this defined European Pharmacopoeia reagent rather than an unspecified potassium iodide preparation. Density is approximately 1 g/cm³ and the boiling point is about 100 °C, consistent with an aqueous iodide preparation. A 100 ml pack suits pharmaceutical quality-control and research laboratories working from Ph. Eur. reagent lists. Physical data from manufacturer Carl ROTH specify molar mass 166,00 g/mol, density ~1 g/cm³ and boiling point ~100 °C. Within the Reagents 4.1.1 series, this saturated potassium iodide solution is selected where the pharmacopoeia stipulates that reagent for identity, purity or related procedures. It is grouped with chemicals in pharmacopoeia quality and with reagents and volumetric standard solutions of the European Pharmacopoeia. Use the 100 ml unit according to the relevant Ph. Eur. chapter and validated in-house methods.

Questions about Potassium iodide solution, saturated, Reag. Ph. Eur.
What is this article?
Potassium iodide solution, saturated, Reag. Ph. Eur. is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reagents for analysis (Ph. Eur., ASTM, DIN), inside Analytical standards & reference materials, in Lab chemicals.
A reagent for analysis is a chemical whose impurities are limited so they do not become a signal in a titration, a digestion or a photometric method. Pharmacopoeia, ASTM and DIN names point at different limit lists. The grade, not only the identity, is the purchase.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
