Description
Ursolic acid methyl ester is a methylated triterpenoid standard offered as ROTICHROM® HPLC material for high-performance liquid chromatography and related analytical tasks. Identified by CAS number 32208-45-0, empirical formula C₃₁H₅₀O₃ and molar mass 470,74 g/mol, it provides a defined chemical identity for calibration, peak assignment and method verification. The unit contains 10 mg in glass, suited to preparation of stock and working solutions without excess inventory. EG number 250-953-3 supports regulatory and internal documentation. Laboratories use this ester in natural-product chemistry, metabolite studies and comparative chromatography alongside related ursane-type compounds. Supplied from manufacturer Carl ROTH in the ROTICHROM® HPLC range, the product delivers a compact, well-characterised reference for research and quality-control workflows. Apply standard laboratory precautions for handling solid organic reference substances and follow site-specific storage procedures.

Questions about Ursolic acid methyl ester, ROTICHROM® HPLC, 10 mg, glass
What is this article?
Ursolic acid methyl ester, 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.
