Triphenyl(((3ar,5s,5ar,8as,8br)-2,2,7,7-tetramethyltetrahydro-5h-bis([1,3]dioxolo)[4,5-b:4',5'-d]pyran-5-yl)methyl)phosphonium iodide (CAS 69204-28-0), molecular formula C30H34O5PI and molecular weight 632.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Triphenyl(((3ar,5s,5ar,8as,8br)-2,2,7,7-tetramethyltetrahydro-5h-bis([1,3]dioxolo)[4,5-b:4',5'-d]pyran-5-yl)methyl)phosphonium iodide (C30H34O5PI) is characterized by a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage, iodine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Triphenyl(((3ar,5s,5ar,8as,8br)-2,2,7,7-tetramethyltetrahydro-5h-bis([1,3]dioxolo)[4,5-b:4',5'-d]pyran-5-yl)methyl)phosphonium iodide 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.
