Chemical Structure
Description
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.
N-allyl-5-chloro-1-(2,6-dichlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxamide (CAS 339023-87-9) is a high-purity analytical reference standard with the molecular formula C16H13Cl3N2O2 and a molecular weight of 371.65 g/mol.
N-allyl-5-chloro-1-(2,6-dichlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxamide (C16H13Cl3N2O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
