(2R,3R,4S)-2-((benzoyloxy)methyl)-3,4-dihydro-2H-pyran-3,4,5-triyl tribenzoate (CAS 14125-75-8), molecular formula C34H26O9 and molecular weight 578.56 g/mol, is a CATO reference standard with documented purity and traceability.
(2R,3R,4S)-2-((benzoyloxy)methyl)-3,4-dihydro-2H-pyran-3,4,5-triyl tribenzoate (C34H26O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
