3,4-Dichloro-N-(1-(2,6-dichlorobenzyl)-2-oxo-1,2-dihydropyridin-3-yl)benzamide (CAS 338784-11-5), molecular formula C19H12Cl4N2O2 and molecular weight 442.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,4-Dichloro-N-(1-(2,6-dichlorobenzyl)-2-oxo-1,2-dihydropyridin-3-yl)benzamide (C19H12Cl4N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 442.12 g/mol, it falls into the moderately-high-molecular-weight range. 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.
