(14aR)-(2,13-Dimethyl-6,7,8,9-tetrahydrodibenzo[b,d][1,6]dioxecine-1,14-diyl)bis(diphenylphosphine) (CAS 428877-93-4) is a high-purity analytical reference standard with the molecular formula C42H38O2P2 and a molecular weight of 636.70 g/mol.
The molecular framework of (14aR)-(2,13-Dimethyl-6,7,8,9-tetrahydrodibenzo[b,d][1,6]dioxecine-1,14-diyl)bis(diphenylphosphine) (C42H38O2P2) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (14aR)-(2,13-Dimethyl-6,7,8,9-tetrahydrodibenzo[b,d][1,6]dioxecine-1,14-diyl)bis(diphenylphosphine) 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.
