3-{1-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]-1H-pyrrol-2-yl}-2-[(methoxyimino)methyl]acrylonitrile CAS 339278-24-9

Description

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.

3-{1-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]-1H-pyrrol-2-yl}-2-[(methoxyimino)methyl]acrylonitrile (CAS 339278-24-9) is a high-purity analytical reference standard with the molecular formula C15H10ClF3N4O and a molecular weight of 354.71 g/mol.

The molecular framework of 3-{1-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]-1H-pyrrol-2-yl}-2-[(methoxyimino)methyl]acrylonitrile (C15H10ClF3N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
