Description
CDTA is a chelating compound offered at a minimum purity of 99 % for synthesis, with CAS number 125572-95-4 and the empirical formula C₁₄H₂₂N₂O₈ · H₂O. The molar mass is 364,34 g/mol and the density ranges from 1,474 to 1,475 g/cm³. Also known as trans-1,2-diaminocyclohexane-N,N,N′,N′-tetraacetic acid monohydrate, CDTA forms stable complexes with many metal ions and is applied in synthesis, analytical complexometry, and laboratory procedures that require strong sequestering capacity. It is From manufacturer Carl ROTH, the material carries EG nr. 236-308-9 and meets the stated minimum assay for synthesis-grade use. The monohydrate form provides a defined composition for weighing and solution preparation. CDTA is valued where cyclohexane-backbone chelators are preferred for selective metal binding, buffer systems, or intermediate steps in organic and inorganic laboratory workflows.

Questions about CDTA, min. 99 %, for synthesis, 100 g, plastic
What is this article?
CDTA, min. 99 %, for synthesis, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
Which category should I open next?
