(S)-(6,6'-Dimethoxybiphenyl-2,2'-diyl)bis[bis(4-methylphenyl)phosphine] CAS 133545-25-2

Description

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.

(S)-(6,6'-Dimethoxybiphenyl-2,2'-diyl)bis[bis(4-methylphenyl)phosphine] (CAS 133545-25-2), molecular formula C28H26O2P2 and molecular weight 456.45 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-(6,6'-Dimethoxybiphenyl-2,2'-diyl)bis[bis(4-methylphenyl)phosphine] (C28H26O2P2) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures (S)-(6,6'-Dimethoxybiphenyl-2,2'-diyl)bis[bis(4-methylphenyl)phosphine] under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
