Description
Frangulin (A+B) is a phytochemical chromatography standard offered in the ROTICHROM® CHR grade for analytical laboratory use. It is identified by CAS number 60529-33-1 and comprises the related empirical formulas C₂₁H₂₀O₉ and C₂₀H₁₈O₉, with corresponding molar masses of 416,37 g/mol and 402,36 g/mol. Supplied as a 25 mg glass-pack unit, this material is intended for chromatographic reference work, including method setup, peak assignment and comparative analysis of plant-derived anthraquinone glycosides. Laboratories engaged in phytochemical screening, natural-product characterisation and standards-based chromatography benefit from a clearly specified Frangulin (A+B) preparation. The product comes from manufacturer Carl ROTH within the ROTICHROM® CHR range, aligning with workflows that require documented reference substances for qualitative and quantitative studies. Dual formula and molar-mass data reflect the A and B components, supporting accurate recording in analytical documentation. The compact glass presentation suits controlled handling in research and quality-control environments focused on botanical and chromatographic standards.

Questions about Frangulin (A+B), ROTICHROM® CHR, 25 mg, glass
What is this article?
Frangulin (A+B), ROTICHROM® CHR, 25 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.
