9,9-Bis(trifluoromethyl)-2,3,6,7-xanthenetetracarboxylic dianhydride (CAS 139162-14-4) is a high-purity analytical reference standard with the molecular formula C19H4F6O7 and a molecular weight of 458.22 g/mol.
The molecular framework of 9,9-Bis(trifluoromethyl)-2,3,6,7-xanthenetetracarboxylic dianhydride (C19H4F6O7) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. 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.
