Description
Nitrilotriacetic acid is a high-purity chelating reagent supplied at a minimum of 98 % (p.a., ACS) for analytical and preparative laboratory use. The compound has the empirical formula C₆H₉NO₆, a molar mass of 191,14 g/mol and a density of 1,67 g/cm³, with a flash point of 100 °C and a boiling point of 160 °C. CAS number 139-13-9 and EG nr. 205-355-7 identify the material for documentation and regulatory handling. As a classic aminopolycarboxylic acid, it is widely applied in complexometric work, metal-ion binding studies and the preparation of buffered or sequestering reagent systems. The 100 g plastic pack supports convenient dispensing on the bench while protecting the solid during storage. This grade from manufacturer Carl ROTH meets p.a. and ACS expectations suitable for research, method development and quality-control environments. Clear physicochemical data aid stoichiometric calculations and protocol transfer. Nitrilotriacetic acid remains a dependable choice whenever a defined, high-assay chelator is required in inorganic or analytical chemistry workflows.

Questions about Nitrilotriacetic acid, min. 98 %, p.a., ACS, 100 g, plastic
What is this article?
Nitrilotriacetic acid, min. 98 %, p.a., ACS, 100 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.
