Description
Orientin is a flavonoid glycoside offered in ROTICHROM® HPLC grade for analytical and research applications. It is identified by CAS number 28608-75-5 and the empirical formula C₂₁H₂₀O₁₁, with a molar mass of 448,38 g/mol. This material is used as a chromatographic reference in HPLC method development, calibration, peak assignment and quantitative determination of plant polyphenols and related natural products. The pack contains 5 mg in a glass container, supporting accurate preparation of stock and working standards for system suitability and routine analysis. Laboratories performing phytochemical screening, herbal-extract quality control and metabolite profiling benefit from a clearly defined HPLC-grade orientin reference. This preparation from manufacturer Carl ROTH integrates into reverse-phase and other liquid-chromatography workflows where a reliable identity standard is required. Documented chemical composition and molar mass facilitate concentration calculations and method validation. Analytical chemists can apply the product in both research and quality-control protocols that specify orientin as a reference without extending claims beyond the stated ROTICHROM® HPLC designation and listed physicochemical data.

Questions about Orientin, ROTICHROM® HPLC, 5 mg, glass
What is this article?
Orientin, ROTICHROM® HPLC, 5 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.
