Description
Sodium tetraphenylborate is an analytical-grade reagent with a minimum purity of 99,5 % (p.a., ACS), intended for precise laboratory applications. It is characterised by the empirical formula C₂₄H₂₀BNa, a molar mass of 342,23 g/mol, CAS number 143-66-8 and EG nr. 205-605-5. The salt is well established as a precipitating and staining-related reagent, notably in environmental analysis and classical inorganic determinations where tetraphenylborate chemistry is required. This material from manufacturer Carl ROTH supports research, teaching and quality-control laboratories that need a high-assay sodium tetraphenylborate source. Documented identity data simplify registration in laboratory systems and alignment with ACS-oriented protocols. Sodium tetraphenylborate offers a practical, high-purity option for precipitation, reagent preparation and related analytical workflows that rely on a defined organoborate salt.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Sodium tetraphenyl borate, min. 99.5 %, p.a., ACS, 10 g, plastic
What is this article?
Sodium tetraphenyl borate, min. 99.5 %, p.a., ACS, 10 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
