Description
CATO supplies 3-(Trifluoromethyl)phenyl 2-[3-(trifluoromethyl)phenoxy]pyridine-3-carboxylate (CAS 1795491-19-8), a certified reference material (molecular formula C20H11F6NO3, MW 427.30 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H11F6NO3, 3-(Trifluoromethyl)phenyl 2-[3-(trifluoromethyl)phenoxy]pyridine-3-carboxylate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 427.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
