Description

CATO supplies .beta.-D-Glucopyranose, cyclic 2,3:4,6-bis[(1S)-4,4',5,5',6,6'-hexahydroxy[1,1'-biphenyl]-2,2'-dicarboxylate] 1-(3,4,5-trihydroxybenzoate) 1(.beta.)-O-Galloylpedunculagin 79786-00-8 Casuarictin [dodecahydroxy(tetraoxo)[?]yl] 3,4,5-trihydroxybenzoate (CAS 79786-00-8), a certified reference material (molecular formula C41H28O26, MW 936.65 g/mol) for analytical method development and quality control.

The molecular framework of .beta.-D-Glucopyranose, cyclic 2,3:4,6-bis[(1S)-4,4',5,5',6,6'-hexahydroxy[1,1'-biphenyl]-2,2'-dicarboxylate] 1-(3,4,5-trihydroxybenzoate) 1(.beta.)-O-Galloylpedunculagin 79786-00-8 Casuarictin [dodecahydroxy(tetraoxo)[?]yl] 3,4,5-trihydroxybenzoate (C41H28O26) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
