(3-Bromo-4-(trifluoromethoxy)phenyl)(pyridin-4-yl)methanone (CAS 1261882-20-5), molecular formula C13H7BrF3NO2 and molecular weight 346.10 g/mol, is a CATO reference standard with documented purity and traceability.
(3-Bromo-4-(trifluoromethoxy)phenyl)(pyridin-4-yl)methanone (C13H7BrF3NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
