CATO supplies (2S,3S,5R,6S)-6-[2-(2-ethyl-5-oxohexoxy)carbonylbenzoyl]oxy-3,4,5-trihydroxyoxane-2-carboxylic acid (CAS 118517-72-9), a certified reference material (molecular formula C22H28O11, MW 468.45 g/mol) for analytical method development and quality control.
The molecular framework of (2S,3S,5R,6S)-6-[2-(2-ethyl-5-oxohexoxy)carbonylbenzoyl]oxy-3,4,5-trihydroxyoxane-2-carboxylic acid (C22H28O11) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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.
