1,1′-(7,8-Dihydro-6H-dibenzo[f,h][1,5]dioxonin-1,13-diyl)bis[1,1-diphenylphosphine] CAS 920317-38-0

Description

1,1′-(7,8-Dihydro-6H-dibenzo[f,h][1,5]dioxonin-1,13-diyl)bis[1,1-diphenylphosphine] (C40H32O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).

1,1′-(7,8-Dihydro-6H-dibenzo[f,h][1,5]dioxonin-1,13-diyl)bis[1,1-diphenylphosphine] (CAS 920317-38-0) is a high-purity analytical reference standard with the molecular formula C40H32O2P2 and a molecular weight of 606.63 g/mol.

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), 1,1′-(7,8-Dihydro-6H-dibenzo[f,h][1,5]dioxonin-1,13-diyl)bis[1,1-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.
