Chemical Structure
Description
The occurrence of N-(4-chlorobenzyl)-1-((2,2-difluorobenzo[d][1,3]dioxol-5-yl)methyl)-2-oxo-1,2-dihydropyridine-3-carboxamide is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(4-chlorobenzyl)-1-((2,2-difluorobenzo[d][1,3]dioxol-5-yl)methyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (CAS 400083-05-8), molecular formula C21H15ClF2N2O4 and molecular weight 432.80 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, N-(4-chlorobenzyl)-1-((2,2-difluorobenzo[d][1,3]dioxol-5-yl)methyl)-2-oxo-1,2-dihydropyridine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
