Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1,16-Bis(diphenylphosphino)-6,7,8,9,10,11-hexahydrodibenzo[b,d][1,6]dioxacyclododecine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 636.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1,16-Bis(diphenylphosphino)-6,7,8,9,10,11-hexahydrodibenzo[b,d][1,6]dioxacyclododecine (CAS 905714-10-5), molecular formula C42H38O2P2 and molecular weight 636.70 g/mol, is a CATO reference standard with documented purity and traceability.
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.
