Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 483.34 g/mol gives 4-Chloro-2-(3-chlorophenyl)-5-(4-((4-fluorophenyl)sulfonyl)piperazin-1-yl)pyridazin-3(2H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Chloro-2-(3-chlorophenyl)-5-(4-((4-fluorophenyl)sulfonyl)piperazin-1-yl)pyridazin-3(2H)-one (CAS 477867-39-3), a certified reference material (molecular formula C20H17Cl2FN4O3S, MW 483.34 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-2-(3-chlorophenyl)-5-(4-((4-fluorophenyl)sulfonyl)piperazin-1-yl)pyridazin-3(2H)-one (C20H17Cl2FN4O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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).
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 4-Chloro-2-(3-chlorophenyl)-5-(4-((4-fluorophenyl)sulfonyl)piperazin-1-yl)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.
