Chemical Structure
Description
The occurrence of Bis(3-(trifluoromethyl)phenyl)phosphine oxide is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Bis(3-(trifluoromethyl)phenyl)phosphine oxide (CAS 15929-44-9), a certified reference material (molecular formula C14H8F6OP, MW 337.18 g/mol) for analytical method development and quality control.
Bis(3-(trifluoromethyl)phenyl)phosphine oxide (C14H8F6OP) contains organophosphorus functionality, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
