Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Pyridazine, 3-chloro-6-methoxy-, 2-oxide (CAS 14634-52-7), molecular formula C5H5ClN2O2 and molecular weight 160.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Pyridazine, 3-chloro-6-methoxy-, 2-oxide (C5H5ClN2O2) is characterized by an amide group, a carboxylic acid 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.
CATO manufactures Pyridazine, 3-chloro-6-methoxy-, 2-oxide 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.
