Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Copper, (4-bromo-3-hydroxy-2-naphthoato)(5-chloro-8-quinolinolato)- (CAS 14040-00-7) is a high-purity analytical reference standard with the molecular formula C20H11BrClCuNO4 and a molecular weight of 508.21 g/mol.
Copper, (4-bromo-3-hydroxy-2-naphthoato)(5-chloro-8-quinolinolato)- (C20H11BrClCuNO4) contains a salt form, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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.
