Chemical Structure
Description
4-[(1E)-{[(2-chloro-4-fluorophenyl)methoxy]imino}methyl]-2-methyl-6-oxo-1,4,5,6-tetrahydropyridine-3-carbonitrile (CAS 338392-25-9) is a high-purity analytical reference standard with the molecular formula C15H13ClFN3O2 and a molecular weight of 321.73 g/mol.
Based on its molecular formula C15H13ClFN3O2, 4-[(1E)-{[(2-chloro-4-fluorophenyl)methoxy]imino}methyl]-2-methyl-6-oxo-1,4,5,6-tetrahydropyridine-3-carbonitrile 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 321.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
