Description
Marein is a reference-quality natural product offered as ROTICHROM® HPLC material for chromatographic and analytical work. It is characterised by CAS number 535-96-6, the empirical formula C₂₁H₂₂O₁₁ and a molar mass of 450,40 g/mol. Packed as 5 mg in glass, the small quantity is appropriate for HPLC method development, peak identification and calibration tasks where only limited amounts of pure standard are required. This preparation from manufacturer Carl ROTH supports laboratories that need a defined chalcone glycoside standard with clear molecular identity data. The ROTICHROM® HPLC designation indicates suitability for high-performance liquid chromatography applications in natural-product and phytochemical analysis. Users can incorporate the stated formula and molar mass directly into documentation, stock calculations and spectral or chromatographic comparisons. The compact glass pack keeps the standard convenient to store and dispense in analytical environments.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Marein, ROTICHROM® HPLC, 5 mg, glass
What is this article?
Marein, ROTICHROM® HPLC, 5 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
