Description
Cynarin is a phytochemical reference substance offered in ROTICHROM® HPLC grade for high-performance liquid chromatography and related analytical separations. It is identified by CAS number 1182-34-9, empirical formula C₂₅H₂₄O₁₂, and a molar mass of 516,44 g/mol, giving laboratories a clearly defined marker for method setup and compound verification. The preparation is packed as 10 mg in glass, a format well suited to precise aliquoting, standard preparation, and economical use in chromatographic calibration workflows. As a ROTICHROM® HPLC material from manufacturer Carl ROTH, cynarin supports natural-product analysis, plant-extract profiling, and quality-control tasks where a consistent reference is required. The small glass unit helps protect the solid during storage and transfer while remaining practical for preparing stock solutions at analytical concentrations. Researchers and analysts working with phenolic or artichoke-related constituents can incorporate this standard into validated HPLC methods, system suitability checks, and comparative studies. Documented molecular formula and molar mass facilitate accurate weighing, dilution calculations, and traceable reporting within regulated or research laboratory environments.

Questions about Cynarin, ROTICHROM® HPLC, 10 mg, glass
What is this article?
Cynarin, ROTICHROM® HPLC, 10 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.
Which category should I open next?
The category is Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
