Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 335.74 g/mol gives (E)-2-(4-chlorophenoxy)-4-methoxy-N-((methoxyimino)methyl)nicotinamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(E)-2-(4-chlorophenoxy)-4-methoxy-N-((methoxyimino)methyl)nicotinamide (CAS 339102-10-2), molecular formula C15H14ClN3O4 and molecular weight 335.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-2-(4-chlorophenoxy)-4-methoxy-N-((methoxyimino)methyl)nicotinamide (C15H14ClN3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
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.
