Chemical Structure
Description
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.
CATO supplies 4-Chloro-2-(3-chlorophenyl)-5-(4-(2,6-dinitro-4-(trifluoromethyl)phenyl)piperazin-1-yl)pyridazin-3(2H)-one (CAS 477867-41-7), a certified reference material (molecular formula C21H15Cl2F3N6O5, MW 559.28 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-2-(3-chlorophenyl)-5-(4-(2,6-dinitro-4-(trifluoromethyl)phenyl)piperazin-1-yl)pyridazin-3(2H)-one (C21H15Cl2F3N6O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 559.28 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
