Description
Rhein is an anthraquinone phytochemical reference material in ROTICHROM® CHR quality for chromatographic standards work. It is identified by CAS number 478-43-3, empirical formula C₁₅H₈O₆, molar mass 284,23 g/mol, and EG number 207-521-4. The 50 mg glass pack is suited to calibration, identification, and comparative analysis in HPLC and related separation techniques focused on plant-derived anthraquinones. Laboratories use rhein in phytochemical profiling, natural-product research, and method development where a defined CHR-grade standard is required. Small-quantity packaging supports efficient preparation of reference solutions while limiting surplus material. Supplied from manufacturer Carl ROTH as part of the ROTICHROM® CHR line, it fits analytical workflows that demand traceable identity data. CAS, formula, and molar-mass details on the product support accurate recording in laboratory information systems and quality documentation for chromatography standards and phytochemical analysis.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Rhein, ROTICHROM® CHR, 50 mg, glass
What is this article?
Rhein, ROTICHROM® CHR, 50 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
