(R)-5-Phenyl-1,3-dioxolane-2,4-dione (CAS 54256-33-6), molecular formula C9H6O4 and molecular weight 178.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-5-Phenyl-1,3-dioxolane-2,4-dione (C9H6O4) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
