Description

The occurrence of 1140-81-4 A803130 N-(2-methyl-4-oxidanylidene-1H-quinolin-6-yl)ethanamide N-(2-methyl-4-oxo-1H-quinolin-6-yl)acetamide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1140-81-4 A803130 N-(2-methyl-4-oxidanylidene-1H-quinolin-6-yl)ethanamide N-(2-methyl-4-oxo-1H-quinolin-6-yl)acetamide (CAS 1140-81-4), a certified reference material (molecular formula C12H12N2O2, MW 216.24 g/mol) for analytical method development and quality control.

1140-81-4 A803130 N-(2-methyl-4-oxidanylidene-1H-quinolin-6-yl)ethanamide N-(2-methyl-4-oxo-1H-quinolin-6-yl)acetamide (C12H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
