Chemical Structure
Description
The molecular framework of 2-Benzyl-6-chloro-[1,2,4]triazolo[4,3-b]pyridazin-3(2H)-one (C12H9ClN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-Benzyl-6-chloro-[1,2,4]triazolo[4,3-b]pyridazin-3(2H)-one (CAS 477851-95-9) is a high-purity analytical reference standard with the molecular formula C12H9ClN4O and a molecular weight of 260.68 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
