Description
(+)-Usnic acid is a phytochemical chromatography standard supplied in ROTICHROM® CHR grade for analytical and research applications. The compound carries CAS number 7562-61-0 and EG nr. 231-456-0, with empirical formula C₁₈H₁₆O₇, molar mass 344,31 g/mol, and density 1,54 g/cm³. Packaged as 10 g in plastic, this quantity suits repeated preparation of reference solutions, system suitability checks, and comparative studies of lichen-derived secondary metabolites. Offered by manufacturer Carl ROTH within the standards-for-chromatography range, (+)-usnic acid supports phytochemical analysis, natural-product characterisation, and method work where a defined enantiomeric form is specified. Clear identity data—CAS, EG number, formula, and molar mass—facilitate documentation, stoichiometric calculations, and inventory control in analytical laboratories. The plastic pack format is practical for routine bench handling while preserving the material for ongoing chromatographic and spectroscopic investigations of usnic acid and related structures.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about (+)-Usnic acid, ROTICHROM® CHR, 10 g, plastic
What is this article?
(+)-Usnic acid, ROTICHROM® CHR, 10 g, plastic 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.
