Description
Sennoside B is a high-purity reference substance in the ROTICHROM® HPLC line, intended for analytical chromatography and natural-product characterisation. It is specified with CAS number 128-57-4, empirical formula C₄₂H₃₈O₂₀, molar mass 862,72 g/mol and EG nr. 204-895-0. Supplied as 10 mg in glass, the pack is practical for establishing calibration standards, verifying retention behaviour and supporting quantitative HPLC of sennoside isomers. Laboratories engaged in herbal-drug analysis, extract profiling or method validation use this material when a discrete sennoside B reference is needed alongside related markers. Available from manufacturer Carl ROTH, the product helps maintain consistent analytical results across batches and instruments. Its defined identity and HPLC-oriented grade make it a reliable choice for routine and research applications involving senna constituents.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

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