Chemical Structure
Description
The occurrence of (S)-5,5'-Heptamethylenedioxy-2,2'-bis(diphenylphosphino) biphenyl 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)-5,5'-Heptamethylenedioxy-2,2'-bis(diphenylphosphino) biphenyl (CAS 1225281-41-3), molecular formula C43H40O2P2 and molecular weight 650.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-5,5'-Heptamethylenedioxy-2,2'-bis(diphenylphosphino) biphenyl (C43H40O2P2) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 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.
CATO manufactures (S)-5,5'-Heptamethylenedioxy-2,2'-bis(diphenylphosphino) biphenyl 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.
