Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 1-(3-Chlorophenyl)-4-hydroxy-5-iodo-6-oxo-1,6-dihydropyridazine-3-carboxylic acid (CAS 383148-80-9), a certified reference material (molecular formula C11H6ClIN2O4, MW 392.53 g/mol) for analytical method development and quality control.
1-(3-Chlorophenyl)-4-hydroxy-5-iodo-6-oxo-1,6-dihydropyridazine-3-carboxylic acid (C11H6ClIN2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
