Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.23 g/mol gives 3-Methoxy-3'-(trifluoromethyl)-[1,1'-biphenyl]-4-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Methoxy-3'-(trifluoromethyl)-[1,1'-biphenyl]-4-ol (CAS 1261990-39-9), a certified reference material (molecular formula C14H11F3O2, MW 268.23 g/mol) for analytical method development and quality control.
3-Methoxy-3'-(trifluoromethyl)-[1,1'-biphenyl]-4-ol (C14H11F3O2) contains a carboxylic acid group, 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, the carboxyl group imparts weak acidity; 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).
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.
