Chemical Structure
Description
The molecular framework of ((2R,3S,4R,5S)-3,4,5-Trihydroxytetrahydro-2H-pyran-2-yl)methyl 3,4,5-trihydroxybenzoate (C13H16O9) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
((2R,3S,4R,5S)-3,4,5-Trihydroxytetrahydro-2H-pyran-2-yl)methyl 3,4,5-trihydroxybenzoate (CAS 82151-97-1), molecular formula C13H16O9 and molecular weight 316.26 g/mol, is a CATO reference standard with documented purity and traceability.
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.
