Compared with other compounds in its class, the molecular weight of 350.72 g/mol gives 3-Chloro-N-({3-[(1E)-1-(methoxyimino)ethyl]-4,5-dihydro-1,2-oxazol-5-yl}methyl)-5-(trifluoromethyl)pyridin-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Chloro-N-({3-[(1E)-1-(methoxyimino)ethyl]-4,5-dihydro-1,2-oxazol-5-yl}methyl)-5-(trifluoromethyl)pyridin-2-amine (CAS 344276-92-2), molecular formula C13H14ClF3N4O2 and molecular weight 350.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-N-({3-[(1E)-1-(methoxyimino)ethyl]-4,5-dihydro-1,2-oxazol-5-yl}methyl)-5-(trifluoromethyl)pyridin-2-amine (C13H14ClF3N4O2) 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. 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.
