Chemical Structure
Description
The occurrence of Diphenyl(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.
CATO supplies Diphenyl(4-(trifluoromethyl)phenyl)phosphane (CAS 13406-28-5), a certified reference material (molecular formula C19H14F3P, MW 330.28 g/mol) for analytical method development and quality control.
Diphenyl(4-(trifluoromethyl)phenyl)phosphane (C19H14F3P) contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
As a certified reference material (CRM), Diphenyl(4-(trifluoromethyl)phenyl)phosphane 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.
