Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Chloro-N-(1-(2,6-dichlorobenzyl)-2-oxo-1,2-dihydropyridin-3-yl)benzamide (CAS 338784-47-7) is a high-purity analytical reference standard with the molecular formula C19H13Cl3N2O2 and a molecular weight of 407.68 g/mol.
2-Chloro-N-(1-(2,6-dichlorobenzyl)-2-oxo-1,2-dihydropyridin-3-yl)benzamide (C19H13Cl3N2O2) contains a steroid core, 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.
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.
