Phosphine, 1,1′-[(1S)-6,6′-dimethoxy[1,1′-biphenyl]-2,2′-diyl]bis[1,1-bis(4-chlorophenyl)- CAS 1310054-14-8

Description

Phosphine, 1,1′-[(1S)-6,6′-dimethoxy[1,1′-biphenyl]-2,2′-diyl]bis[1,1-bis(4-chlorophenyl)- (CAS 1310054-14-8) is a high-purity analytical reference standard with the molecular formula C38H28Cl4O2P2 and a molecular weight of 720.39 g/mol.

Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, Phosphine, 1,1′-[(1S)-6,6′-dimethoxy[1,1′-biphenyl]-2,2′-diyl]bis[1,1-bis(4-chlorophenyl)- is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 720.39 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).

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.

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.
