Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-chlorophenyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid.
CATO supplies 1-(3-chlorophenyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid (CAS 1284635-72-8), a certified reference material (molecular formula C12H8ClNO3, MW 249.65 g/mol) for analytical method development and quality control.
Structurally, 1-(3-chlorophenyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid (C12H8ClNO3) 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 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 249.65 g/mol, it falls into the medium-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.
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.
