4,5-Dichloro-2-[(2-chlorophenyl)methyl]-2,3-dihydropyridazin-3-one CAS 112749-52-7 chemical structure

Description

The occurrence of 4,5-Dichloro-2-[(2-chlorophenyl)methyl]-2,3-dihydropyridazin-3-one is closely related to a nitrogen-containing heterocyclic scaffold, 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 4,5-Dichloro-2-[(2-chlorophenyl)methyl]-2,3-dihydropyridazin-3-one (CAS 112749-52-7), a certified reference material (molecular formula C11H7Cl3N2O, MW 289.55 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H7Cl3N2O, 4,5-Dichloro-2-[(2-chlorophenyl)methyl]-2,3-dihydropyridazin-3-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 289.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 4,5-Dichloro-2-[(2-chlorophenyl)methyl]-2,3-dihydropyridazin-3-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.
