(11aR)-1,10-bis(3,5-bis(trifluoromethyl)phenyl)-12-hydroxy-3,8-dimethyl-4,5,6,7-tetrahydrodiindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocine 12-oxide (CAS 2098225-20-6), molecular formula C35H23F12O4P and molecular weight 766.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (11aR)-1,10-bis(3,5-bis(trifluoromethyl)phenyl)-12-hydroxy-3,8-dimethyl-4,5,6,7-tetrahydrodiindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocine 12-oxide (C35H23F12O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
As a certified reference material (CRM), (11aR)-1,10-bis(3,5-bis(trifluoromethyl)phenyl)-12-hydroxy-3,8-dimethyl-4,5,6,7-tetrahydrodiindeno[7,1-de:1',7'-fg][1,3,2]dioxaphosphocine 12-oxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
