Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 484.69 g/mol gives 1-(4-Bromophenyl)-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(4-Bromophenyl)-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethan-1-one (CAS 339020-10-9), molecular formula C21H14BrClF3NO2 and molecular weight 484.69 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Bromophenyl)-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethan-1-one (C21H14BrClF3NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. 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 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 1-(4-Bromophenyl)-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethan-1-one 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.
