6-((4-Chlorophenyl)amino)pyridazin-3(2H)-one CAS 3889-35-8

Description

6-((4-Chlorophenyl)amino)pyridazin-3(2H)-one (CAS 3889-35-8), molecular formula C10H8ClN3O and molecular weight 221.64 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H8ClN3O, 6-((4-Chlorophenyl)amino)pyridazin-3(2H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 6-((4-Chlorophenyl)amino)pyridazin-3(2H)-one 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.
