(2R,3R,4S,5R,6R)-2-(acetoxymethyl)-4-hydroxy-6-methoxytetrahydro-2H-pyran-3,5-diyl diacetate CAS 19464-78-9

Description

The molecular framework of (2R,3R,4S,5R,6R)-2-(acetoxymethyl)-4-hydroxy-6-methoxytetrahydro-2H-pyran-3,5-diyl diacetate (C13H20O9) 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 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).
