The occurrence of (11aS)-Dibenzo[d,f][1,3]dioxepin-1,11-diylbis[diphenylphosphine] is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (11aS)-Dibenzo[d,f][1,3]dioxepin-1,11-diylbis[diphenylphosphine] (CAS 486429-92-9), a certified reference material (molecular formula C37H28O2P2, MW 566.56 g/mol) for analytical method development and quality control.
Structurally, (11aS)-Dibenzo[d,f][1,3]dioxepin-1,11-diylbis[diphenylphosphine] (C37H28O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 566.56 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), (11aS)-Dibenzo[d,f][1,3]dioxepin-1,11-diylbis[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.
