Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (6,10-Dihydro-4H-fluoreno[4,5-cde]oxepine-10,10-diyl)bis(diphenylphosphine).
(6,10-Dihydro-4H-fluoreno[4,5-cde]oxepine-10,10-diyl)bis(diphenylphosphine) (CAS 121772-83-6), molecular formula C39H30OP2 and molecular weight 576.60 g/mol, is a CATO reference standard with documented purity and traceability.
(6,10-Dihydro-4H-fluoreno[4,5-cde]oxepine-10,10-diyl)bis(diphenylphosphine) (C39H30OP2) contains organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
