Description
Harpagoside is a ROTICHROM® HPLC reference substance intended for analytical laboratory use. It is specified under CAS number 19210-12-9 and EG number 242-881-6, with the empirical formula C₂₄H₃₀O₁₁ and a molar mass of 494,48 g/mol. The small unit quantity is practical for reference collections, method validation and laboratories that prefer limited working stocks. Formula and molar-mass data enable accurate preparation of stock and calibration solutions and straightforward cross-checking against monographs or in-house specifications. This preparation comes from manufacturer Carl ROTH as part of the ROTICHROM® HPLC line, offering a uniform grade designation alongside related chromatographic standards. Explicit CAS and EG labelling streamlines purchasing, inventory control and regulatory documentation.
This article belongs on HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

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