1-(5-(((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-4,5-dihydroisoxazol-3-yl)ethan-1-one CAS 338422-57-4

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.

1-(5-(((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-4,5-dihydroisoxazol-3-yl)ethan-1-one (CAS 338422-57-4) is a high-purity analytical reference standard with the molecular formula C12H11ClF3N3O2 and a molecular weight of 321.68 g/mol.

Based on its molecular formula C12H11ClF3N3O2, 1-(5-(((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-4,5-dihydroisoxazol-3-yl)ethan-1-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 321.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
