Description
Ginsenoside Rb₂ is a ginseng saponin standard supplied in ROTICHROM® HPLC quality for analytical chromatography and related laboratory applications. Identity data comprise CAS number 11021-13-9, empirical formula C₅₃H₉₀O₂₂, molar mass 1079,28 g/mol and EG number 234-251-4. The 10 mg glass pack provides a practical quantity for preparing reference solutions, calibration series and method-validation samples in HPLC or hyphenated techniques. As a characteristic Panax constituent, ginsenoside Rb₂ is employed in phytochemical fingerprinting, herbal raw-material control and research on ginsenoside profiles where a defined Rb₂ marker is essential. This ROTICHROM® HPLC material from manufacturer Carl ROTH is intended for laboratories that need a clearly specified saponin standard without large bulk quantities. Glass primary packaging supports orderly storage and handling of the solid before use, and the documented CAS, formula and molar-mass values assist traceability, LIMS registration and consistent reporting across analytical workflows in research and quality environments.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Ginsenoside Rb2, ROTICHROM® HPLC, 10 mg, glass
What is this article?
Ginsenoside Rb2, 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.
