CATO supplies N-Cyclopropyl-1-[(3,4-dichlorophenyl)methyl]-2-oxo-1,2-dihydropyridine-3-carboxamide (CAS 338783-55-4), a certified reference material (molecular formula C16H14Cl2N2O2, MW 337.20 g/mol) for analytical method development and quality control.
Structurally, N-Cyclopropyl-1-[(3,4-dichlorophenyl)methyl]-2-oxo-1,2-dihydropyridine-3-carboxamide (C16H14Cl2N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 337.20 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
