Description
(-)-Epigallocatechin gallate is a ROTICHROM® HPLC reference substance supplied as a 10 mg portion in glass for high-performance liquid chromatography and related analytical work. It carries CAS number 989-51-5 and the empirical formula C₂₂H₁₈O₁₁, with a molar mass of 458,36 g/mol. This catechin gallate is widely applied as a phytochemical standard when laboratories need a defined identity for calibration, method verification, or comparative chromatography of polyphenols. The ROTICHROM® HPLC designation indicates suitability for chromatographic purity assessment and quantitative workflows. From manufacturer Carl ROTH, the compact glass pack supports economical use in research and quality-control settings that handle tea polyphenols and related natural products. Clear molecular data and CAS registration aid documentation in analytical reports. The 10 mg unit quantity is convenient for preparing stock solutions and running HPLC sequences without unnecessary surplus material on the bench.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about (-)-Epigallocatechin gallate, ROTICHROM® HPLC, 10 mg, glass
What is this article?
(-)-Epigallocatechin gallate, 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.
