Description
EDTA dipotassium salt dihydrate is a synthesis-grade ethylenediaminetetraacetate salt offered at min. 99 % purity, with CAS number 25102-12-9 and empirical formula C₁₀H₁₄K₂N₂O₈ · 2 H₂O. The molar mass is 404,47 g/mol and the EG number is 217-895-0. As a potassium EDTA salt dihydrate, it serves as a soluble chelating agent for binding divalent and polyvalent metal ions in synthesis, sample preparation and laboratory buffer systems. The product is Available from manufacturer Carl ROTH for synthesis use, it supports workflows that need a defined dipotassium EDTA dihydrate with clear assay and registry data. Applications include metal sequestration, complexometric support steps and preparation of chelating stock solutions where potassium counter-ions are preferred. Choose this material when min. 99 % purity, dihydrate stoichiometry and documented CAS/EG identifiers are essential for controlled laboratory practice.

Questions about EDTA dipotassium salt dihydrate, min. 99 %, for synthesis, 250 g, plastic
What is this article?
EDTA dipotassium salt dihydrate, min. 99 %, for synthesis, 250 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
