Description
Fast sulphon black F (C.I. 26990) is an analytical-grade metal indicator supplied at a minimum purity of 95 %, p.a., with CAS number 3682-47-1. The dye has the empirical formula C₃₀H₁₇N₄O₁₁S₃Na₃ and a molar mass of 774,6 g/mol, supporting reliable complexometric and metal-ion indication work in the laboratory. This grade is As a classical metal indicator, Fast sulphon black F is used in titrimetric and related procedures for visualising endpoint changes associated with selected metal ions. The material is positioned among analytical chemicals and metal indicators and is available from manufacturer Carl ROTH for routine laboratory use. The combination of defined purity, known molecular identity and convenient small-pack format makes the product practical for method development, teaching laboratories and quality-control workflows that rely on colour-based metal indication. Handle and store according to laboratory good practice and the accompanying safety documentation.

Questions about Fast sulphon black F (C.I. 26990), min. 95 %, p.a., 5 g, glass
What is this article?
Fast sulphon black F (C.I. 26990), min. 95 %, p.a., 5 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
