Beschrijving
Oleanolzuur is een pentacyclisch triterpenoïde referentiemateriaal geleverd in ROTICHROM® HPLC-kwaliteit voor analytisch en chromatografisch werk. Het wordt gedefinieerd door CAS-nummer 508-02-1, brutoformule C₃₀H₄₈O₃ en een molaire massa van 456,71 g/mol, met EG-nummer 208-081-6. Deze glazen verpakkingseenheid van 20 mg biedt een compacte hoeveelheid die geschikt is voor methodeontwikkeling, kalibratie en kwalitatieve of kwantitatieve HPLC-toepassingen waarbij een goed gekarakteriseerde fytochemische standaard vereist is. De verbinding wordt op grote schaal gebruikt in natuurproductonderzoek, plantmetabolietprofilering en aanverwante laboratoriumworkflows die afhankelijk zijn van betrouwbare chromatografische referentiesubstanties. Aangeboden door fabrikant Carl ROTH onder de ROTICHROM® HPLC-lijn, ondersteunt het materiaal zowel routine-analytische chemie als gespecialiseerd fytochemisch onderzoek. Duidelijke identificatie via CAS, EG-nummer en molecuulformule helpt laboratoria om standaarden consistent te documenteren in SOP's en rapporten. De kleine glazen presentatie is praktisch voor gecontroleerde dosering en opslag in analytische monsterinventarissen.

Questions about Oleanolic acid, ROTICHROM® HPLC, 20 mg, glas
What is this article?
Oleanolic acid, ROTICHROM® HPLC, 20 mg, glas 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 Chemicaliën.
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 Chemicaliën.
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.
