Chemical Structure
Description
4-([1,1-Biphenyl]-2-yloxy)-3-(trifluoromethyl)-phenylamine (C19H14F3NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
4-([1,1-Biphenyl]-2-yloxy)-3-(trifluoromethyl)-phenylamine (CAS 946662-77-7), molecular formula C19H14F3NO and molecular weight 329.32 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-([1,1-Biphenyl]-2-yloxy)-3-(trifluoromethyl)-phenylamine 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.
