Description
tri-Potassium citrate monohydrate is a high-purity inorganic salt meeting both Ph.Eur. and USP requirements at a minimum assay of 99 %. Identified by CAS number 6100-05-6 and empirical formula C₆H₅K₃O₇·H₂O, it has a molar mass of 324,4 g/mol and a density of 1,98 g/cm³. This monohydrate form is valued in pharmaceutical, analytical, and formulation laboratories as a potassium citrate source for buffering, complexation, and reference preparation work. Applications include preparation of citrate buffer systems, electrolyte and nutrient media components, and general inorganic salt chemistry where dual Ph.Eur./USP compliance is advantageous. The defined molar mass and density support accurate weighing and solution make-up in research, quality control, and process development settings that demand reproducible, well-documented reagents.

Questions about tri-Potassium citrate monohydrate, min. 99 %, Ph.Eur., USP, 500 g, plastic
What is this article?
tri-Potassium citrate monohydrate, min. 99 %, Ph.Eur., USP, 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.
