Description
DL-Catechin hydrate is a phytochemical reference material offered in ROTICHROM® CHR quality with a minimum purity of 96 % for chromatographic and analytical work. It carries CAS number 7295-85-4, EG number 230-731-2 and the empirical formula C₁₅H₁₄O₆ · x H₂O, with a molar mass of 290,28 + x H₂O g/mol. Packed as 1 g in glass, the hydrate form supports quantitative and qualitative applications in natural-product analysis, method development and standard preparation. Catechin-type flavan-3-ols are widely used as markers in plant extract profiling, antioxidant studies and HPLC or TLC calibration. The defined CHR grade from manufacturer Carl ROTH helps laboratories maintain traceable reference stocks for routine and research workflows. Glass packaging protects the solid from moisture uptake and contamination during storage and repeated sampling. This compact unit size is convenient for standards cabinets and for preparing working solutions without excess material. Suitable for analytical chemistry, phytochemical screening and chromatography laboratories requiring a reliable DL-catechin hydrate standard.

Questions about DL-Catechin hydrate, ROTICHROM® CHR, 1 g, glass
What is this article?
DL-Catechin hydrate, ROTICHROM® CHR, 1 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
