Description
CATO manufactures 4-Chloro-5-((2-methoxyethyl)amino)pyridazin-3-ol 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-Chloro-5-((2-methoxyethyl)amino)pyridazin-3-ol (CAS 691867-25-1) is a high-purity analytical reference standard with the molecular formula C7H10ClN3O2 and a molecular weight of 203.63 g/mol.
The molecular framework of 4-Chloro-5-((2-methoxyethyl)amino)pyridazin-3-ol (C7H10ClN3O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
