Description
Barium diphenylamine sulfonate is a high-purity analytical reagent supplied at p.a., ACS grade for demanding laboratory work. With CAS number 6211-24-1 and empirical formula C₂₄H₂₀BaN₂O₆S₂, it has a molar mass of 633,88 g/mol and a density of 0,47 g/cm³. This barium salt of diphenylamine sulfonate is widely used as a redox indicator in volumetric analysis, particularly in dichromate and related titrations where a clear colour change supports reliable endpoint detection. The material is Prepared to p.a., ACS specifications from manufacturer Carl ROTH, it meets established purity expectations for analytical chemistry. EG number 228-278-0 identifies the substance for regulatory and documentation purposes. Its defined physical data and indicator chemistry make it a practical choice for classical wet-chemical assays and standardised analytical protocols in research and industrial laboratories.
This article is part of Inorganic salts, in Inorganic chemicals.

Questions about Barium diphenylamine sulfonate, p.a., ACS, 5 g, plastic
What is this article?
Barium diphenylamine sulfonate, p.a., ACS, 5 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.
