Description
Rhein is an anthraquinone reference standard supplied in ROTICHROM® HPLC quality for laboratory analysis and research. The compound has the empirical formula C₁₅H₈O₆, a molar mass of 284,23 g/mol, CAS number 478-43-3 and EG number 207-521-4. It is packed as 20 mg in glass, giving a convenient quantity for chromatographic calibration and identification work. Rhein is widely used in HPLC method development, qualitative confirmation and quantitative determination of anthraquinone constituents in botanical and pharmaceutical matrices. Available from manufacturer Carl ROTH within the ROTICHROM® HPLC range, this material supports consistent analytical performance in natural-product research, extract profiling and routine quality control. The defined chemical identity and practical pack size help laboratories maintain reliable reference stocks without unnecessary surplus. Rhein is a well-known dihydroxyanthraquinone carboxylic acid and serves as a marker substance when characterising rhubarb-type and related plant materials that contain anthraquinone derivatives.
This article belongs on HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Rhein, ROTICHROM® HPLC, 20 mg, glass
What is this article?
Rhein, ROTICHROM® HPLC, 20 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Produits chimiques de laboratoire et industriels.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
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.
