Description
As a certified reference material (CRM), 4-Bromo-6-chloro-3-methoxypyridazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-Bromo-6-chloro-3-methoxypyridazine (CAS 1445774-08-2) is a high-purity analytical reference standard with the molecular formula C5H4BrClN2O and a molecular weight of 223.46 g/mol.
4-Bromo-6-chloro-3-methoxypyridazine (C5H4BrClN2O) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.
