Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (11aR,13S,14R,15S,15aR)-2,3,4,5,6,7-hexahydroxy-9,17-dioxo-9,11,11a,13,14,15,15a,17-octahydrodibenzo[g,i]pyrano[3,2-b][1,5]dioxacycloundecine-13,14,15-triyl tris(3,4,5-trihydroxybenzoate) 1,2,3-trigalloyl-4,6-hexahydroxydiphenoyl beta-D-glucopyranose 58970-75-5 CHEBI:4916 Cornustannin 2 Tellimagrandin II beta-D-Glucopyranose,cyclic4,6-(4,4',5,5',6,6'-hexahydroxy(1,1'-biphenyl)-2,2'-dicarboxylate)1,2,3-tris(3,4,5-trihydroxybenzoate) eugeniin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 938.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(11aR,13S,14R,15S,15aR)-2,3,4,5,6,7-hexahydroxy-9,17-dioxo-9,11,11a,13,14,15,15a,17-octahydrodibenzo[g,i]pyrano[3,2-b][1,5]dioxacycloundecine-13,14,15-triyl tris(3,4,5-trihydroxybenzoate) 1,2,3-trigalloyl-4,6-hexahydroxydiphenoyl beta-D-glucopyranose 58970-75-5 CHEBI:4916 Cornustannin 2 Tellimagrandin II beta-D-Glucopyranose,cyclic4,6-(4,4',5,5',6,6'-hexahydroxy(1,1'-biphenyl)-2,2'-dicarboxylate)1,2,3-tris(3,4,5-trihydroxybenzoate) eugeniin (CAS 58970-75-5), molecular formula C41H30O26 and molecular weight 938.66 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
