Chemical Structure
Description
Methyl (2S,3S,4S,5R,6S)-3,4,5-tris(benzyloxy)-6-hydroxytetrahydro-2H-pyran-2-carboxylate (CAS 75336-65-1), molecular formula C28H30O7 and molecular weight 478.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl (2S,3S,4S,5R,6S)-3,4,5-tris(benzyloxy)-6-hydroxytetrahydro-2H-pyran-2-carboxylate (C28H30O7) 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.
