Description
CATO manufactures 4,6-Dichloro-3-methoxypyridazine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4,6-Dichloro-3-methoxypyridazine (CAS 112342-58-2) is a high-purity analytical reference standard with the molecular formula C5H4Cl2N2O and a molecular weight of 179.00 g/mol.
The molecular framework of 4,6-Dichloro-3-methoxypyridazine (C5H4Cl2N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
