Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 236.23 g/mol gives 4-Methyl-2'-(trifluoromethyl)-1,1'-biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Methyl-2'-(trifluoromethyl)-1,1'-biphenyl (CAS 145486-55-1), molecular formula C14H11F3 and molecular weight 236.23 g/mol, is a CATO reference standard with documented purity and traceability.
4-Methyl-2'-(trifluoromethyl)-1,1'-biphenyl (C14H11F3) contains 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.
