Description
Cucurbitacin E, ROTICHROM® HPLC is a high-purity chromatographic reference material supplied for analytical applications. It is defined by CAS number 18444-66-1, empirical formula C₃₂H₄₄O₈ and a molar mass of 556,69 g/mol, supporting identification and quantification work where a characterised cucurbitacin E standard is required. The ROTICHROM® HPLC grade is oriented toward liquid-chromatography methods in natural-product, phytochemical and related research settings. Packaged as 10 mg in glass, the unit size suits method development, calibration and confirmatory analyses without excess inventory. Laboratories working across chemical A-to-Z catalogues can integrate this compound into HPLC workflows that demand a documented molecular identity and molar mass. The material is available from manufacturer Carl ROTH for users who need a focused milligram-scale standard. Clear CAS and EG identifiers aid registration in laboratory information systems and safety documentation. This compact glass pack supports precise weighing and solution preparation for chromatographic standards in academic, industrial and contract analytical environments.

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