(2R,3R,4S,5S,6S)-2-(Acetoxymethyl)-6-hydroxytetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 22860-22-6), molecular formula C14H20O10 and molecular weight 348.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2R,3R,4S,5S,6S)-2-(Acetoxymethyl)-6-hydroxytetrahydro-2H-pyran-3,4,5-triyl triacetate (C14H20O10) 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).
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.
