Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 325.19 g/mol gives 1-(2-(2,4-Dichlorophenoxy)ethyl)-2-methyl-6-oxo-1,4,5,6-tetrahydropyridine-3-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2-(2,4-Dichlorophenoxy)ethyl)-2-methyl-6-oxo-1,4,5,6-tetrahydropyridine-3-carbonitrile (CAS 338748-80-4), molecular formula C15H14Cl2N2O2 and molecular weight 325.19 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-(2,4-Dichlorophenoxy)ethyl)-2-methyl-6-oxo-1,4,5,6-tetrahydropyridine-3-carbonitrile (C15H14Cl2N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
