Description
Emodin is a phytochemical reference standard supplied as ROTICHROM® CHR grade for chromatographic and analytical work. It carries CAS number 518-82-1, EG number 208-258-8, the empirical formula C₁₅H₁₀O₅ and a molar mass of 270,23 g/mol, giving laboratories a clearly defined anthraquinone marker for identification and quantification. The material is positioned among chromatography standards and phytochemicals and is well suited to HPLC, TLC and related separation techniques where a reliable emodin reference is required. Offered by manufacturer Carl ROTH, the product supports natural-product research, herbal extract characterisation and teaching laboratories that need a consistent, documented standard. Use it to prepare stock solutions, verify retention behaviour or confirm peak identity without introducing unnecessary bulk into the workflow. Clear labelling of CAS, formula and molar mass simplifies documentation and inventory control in regulated and research environments alike.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Emodin, ROTICHROM® CHR, 100 mg, glass
What is this article?
Emodin, ROTICHROM® CHR, 100 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.
