Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 267.11 g/mol gives N4-(2-chlorophenyl)-2-chloroisonicotinamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N4-(2-chlorophenyl)-2-chloroisonicotinamide (CAS 680217-40-7), a certified reference material (molecular formula C12H8Cl2N2O, MW 267.11 g/mol) for analytical method development and quality control.
N4-(2-chlorophenyl)-2-chloroisonicotinamide (C12H8Cl2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
