Chemical Structure
Description
4-[(4-Chloro-1-naphthyl)oxy]-2-(trifluoromethyl)-phenylamine (CAS 946663-34-9) is a high-purity analytical reference standard with the molecular formula C17H11ClF3NO and a molecular weight of 337.72 g/mol.
4-[(4-Chloro-1-naphthyl)oxy]-2-(trifluoromethyl)-phenylamine (C17H11ClF3NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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).
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.
CATO manufactures 4-[(4-Chloro-1-naphthyl)oxy]-2-(trifluoromethyl)-phenylamine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
