4,6-Bis(diphenylphosphino)-10-phenyl-10H-phenoxaphosphine CAS 261733-09-9

Description

Compared with other compounds in its class, the molecular weight of 644.62 g/mol gives 4,6-Bis(diphenylphosphino)-10-phenyl-10H-phenoxaphosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4,6-Bis(diphenylphosphino)-10-phenyl-10H-phenoxaphosphine (CAS 261733-09-9), a certified reference material (molecular formula C42H31OP3, MW 644.62 g/mol) for analytical method development and quality control.

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4,6-Bis(diphenylphosphino)-10-phenyl-10H-phenoxaphosphine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 644.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
