Chemical Structure

3-Benzoyl-5-(4-chlorophenyl)pyridazin-4(1H)-one CAS 90054-43-6 chemical structure

Description

The occurrence of 3-Benzoyl-5-(4-chlorophenyl)pyridazin-4(1H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Benzoyl-5-(4-chlorophenyl)pyridazin-4(1H)-one (CAS 90054-43-6), a certified reference material (molecular formula C17H11ClN2O2, MW 310.73 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Benzoyl-5-(4-chlorophenyl)pyridazin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 3-Benzoyl-5-(4-chlorophenyl)pyridazin-4(1H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
