3-((3,6-Dichloropyridazin-4-yl)thio)pyridazin-4-amine (CAS 55271-67-5), molecular formula C8H5Cl2N5S and molecular weight 274.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((3,6-Dichloropyridazin-4-yl)thio)pyridazin-4-amine (C8H5Cl2N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.
