Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 3,6-dichloro-5-methylpyridazine-4-carboxylate (CAS 2091712-01-3) is a high-purity analytical reference standard with the molecular formula C8H8Cl2N2O2 and a molecular weight of 235.07 g/mol.
The molecular framework of Ethyl 3,6-dichloro-5-methylpyridazine-4-carboxylate (C8H8Cl2N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Ethyl 3,6-dichloro-5-methylpyridazine-4-carboxylate 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.
