Chemical Structure
Description
The occurrence of Phenylbis(4-(trifluoromethyl)phenyl)phosphane is closely related to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Phenylbis(4-(trifluoromethyl)phenyl)phosphane (CAS 39134-71-9), molecular formula C20H13F6P and molecular weight 398.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Phenylbis(4-(trifluoromethyl)phenyl)phosphane (C20H13F6P) is characterized by organophosphorus functionality, fluorine substitution, 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 Phenylbis(4-(trifluoromethyl)phenyl)phosphane 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.
