Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-(6-Chloro-3-oxo-2,3-dihydropyridazin-4-yl)acetamide (CAS 100367-79-1), a certified reference material (molecular formula C6H6ClN3O2, MW 187.58 g/mol) for analytical method development and quality control.
N-(6-Chloro-3-oxo-2,3-dihydropyridazin-4-yl)acetamide (C6H6ClN3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
