Description
EDTA tetrasodium salt dihydrate is a chelating reagent with a minimum purity of 99 %, CAS number 10378-23-1, and the empirical formula C₁₀H₁₂N₂Na₄O₈ · 2 H₂O. The molar mass is 416,2 g/mol and the flash point is above 100 °C. This tetrasodium dihydrate form of ethylenediaminetetraacetic acid is used to complex divalent and trivalent metal ions in buffer preparation, sample work-up, molecular biology, and analytical chemistry. It supports metal-ion masking, titration procedures, and controlled sequestration where a defined stoichiometry is required. The material is Available from manufacturer Carl ROTH, the product is identified under EG nr. 200-573-9 and is specified at the stated minimum assay for synthesis and general laboratory use. Consistent composition of the dihydrate salt aids accurate molar calculations when formulating reagents for research, quality control, and routine complexometric applications.

Questions about EDTA tetrasodium salt dihydrate, min. 99 %, 250 g, plastic
What is this article?
EDTA tetrasodium salt dihydrate, min. 99 %, 250 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biochemicals (other), inside Biochemicals & reagents, in Microbiology lab supplies.
These are the biochemical reagents that are not an amino acid, a sugar, a lipid, an enzyme or an antibiotic. Identity and purity still decide the bottle. If the compound is light-sensitive or hygroscopic, the handling on the label is part of the specification.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
Which category should I open next?
