Description

The occurrence of (<I>R</I>)-(4,4′,6,6′-Tetramethoxybiphenyl-2,2′-diyl)bis(bis(3,5-di-<I>tert</I>- butyl-4-methoxyphenyl)phosphine is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(<I>R</I>)-(4,4′,6,6′-Tetramethoxybiphenyl-2,2′-diyl)bis(bis(3,5-di-<I>tert</I>- butyl-4-methoxyphenyl)phosphine (CAS 1365531-98-1) is a high-purity analytical reference standard with the molecular formula C76H144O8P2 and a molecular weight of 1247.90 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (<I>R</I>)-(4,4′,6,6′-Tetramethoxybiphenyl-2,2′-diyl)bis(bis(3,5-di-<I>tert</I>- butyl-4-methoxyphenyl)phosphine is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1247.90 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.
