Chemical Structure

(<I>S</I>)-(-)-(6,6′-dimethoxybiphenyl-2,2′-diyl)bis(diphenylphosphine) CAS 133545-17-2 chemical structure

Description

As a certified reference material (CRM), (<I>S</I>)-(-)-(6,6′-dimethoxybiphenyl-2,2′-diyl)bis(diphenylphosphine) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(<I>S</I>)-(-)-(6,6′-dimethoxybiphenyl-2,2′-diyl)bis(diphenylphosphine) (CAS 133545-17-2) is a high-purity analytical reference standard with the molecular formula C38H68O2P2 and a molecular weight of 618.89 g/mol.

(<I>S</I>)-(-)-(6,6′-dimethoxybiphenyl-2,2′-diyl)bis(diphenylphosphine) (C38H68O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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).

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.
