Chemical Structure
Description
CATO supplies 4-Chloro-N-(5-methyl-2-oxo-2H-pyrano[3,2-c]pyridin-3-yl)benzamide (CAS 341966-08-3), a certified reference material (molecular formula C16H11ClN2O3, MW 314.72 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-N-(5-methyl-2-oxo-2H-pyrano[3,2-c]pyridin-3-yl)benzamide (C16H11ClN2O3) 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 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 314.72 g/mol, it falls into the moderately-high-molecular-weight range. 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.
