Chemical Structure
Description
The occurrence of (S)-(6,6'-Dimethoxybiphenyl-2,2'-diyl)bis[bis(3,5-di-tert-butylphenyl)phosphine] is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-(6,6'-Dimethoxybiphenyl-2,2'-diyl)bis[bis(3,5-di-tert-butylphenyl)phosphine] (CAS 167709-31-1) is a high-purity analytical reference standard with the molecular formula C42H54O2P2 and a molecular weight of 652.82 g/mol.
(S)-(6,6'-Dimethoxybiphenyl-2,2'-diyl)bis[bis(3,5-di-tert-butylphenyl)phosphine] (C42H54O2P2) 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).
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.
