Description
Coumarin ROTICHROM® GC is a gas-chromatography reference substance with empirical formula C₉H₆O₂, CAS number 91-64-5 and EG number 202-086-7. The molar mass is 146,15 g/mol, density 0,935 g/cm³, flash point 162 °C and boiling point 298 °C. Packed as 1 g in glass, this lactone is intended for GC calibration, retention-index work and qualitative or quantitative reference applications in chromatographic laboratories. The ROTICHROM® GC grade from manufacturer Carl ROTH is positioned for analytical workflows that demand defined identity and consistent performance as a reference material. Coumarin is frequently used when establishing system suitability, verifying detector response or supporting method development in fragrance, natural-product and organic-analysis contexts. The small 1 g glass unit minimises waste while providing sufficient material for repeated standard preparation. Store and handle under controlled laboratory conditions appropriate to organic solids, and consult the safety documentation for classification, UN handling notes and recommended precautions before opening the vial or preparing solutions.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Coumarin, ROTICHROM® GC, 1 g, glass
What is this article?
Coumarin, ROTICHROM® GC, 1 g, 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.
