Description

Compared with other compounds in its class, the molecular weight of 394.77 g/mol gives 3-(Benzyloxy)-3'-chloro-2-methyl-5'-(trifluoromethyl)-4H-[1,2'-bipyridine]-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(Benzyloxy)-3'-chloro-2-methyl-5'-(trifluoromethyl)-4H-[1,2'-bipyridine]-4-one (CAS 338965-50-7), molecular formula C19H14ClF3N2O2 and molecular weight 394.77 g/mol, is a CATO reference standard with documented purity and traceability.

3-(Benzyloxy)-3'-chloro-2-methyl-5'-(trifluoromethyl)-4H-[1,2'-bipyridine]-4-one (C19H14ClF3N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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).

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.

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.
