Compared with other compounds in its class, the molecular weight of 400.35 g/mol gives (E)-4-methoxy-2-(2-((((3-(trifluoromethyl)benzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)nicotinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (E)-4-methoxy-2-(2-((((3-(trifluoromethyl)benzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)nicotinonitrile (CAS 339103-21-8), a certified reference material (molecular formula C20H15F3N4O2, MW 400.35 g/mol) for analytical method development and quality control.
The molecular framework of (E)-4-methoxy-2-(2-((((3-(trifluoromethyl)benzyl)oxy)imino)methyl)-1H-pyrrol-1-yl)nicotinonitrile (C20H15F3N4O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
