Chemical Structure
Description
The molecular framework of 8-Chloro-[1,2,4]triazolo[4,3-b]pyridazin-7-amine (C5H4ClN5) is characterized by a nitrile group, 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.
8-Chloro-[1,2,4]triazolo[4,3-b]pyridazin-7-amine (CAS 89284-31-1), molecular formula C5H4ClN5 and molecular weight 169.57 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
