Chemical Structure

6-(4-Bromophenyl)-4-(4-chlorophenyl)-4,5-dihydropyridazin-3(2H)-one CAS 344282-69-5 chemical structure

Description

The occurrence of 6-(4-Bromophenyl)-4-(4-chlorophenyl)-4,5-dihydropyridazin-3(2H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-(4-Bromophenyl)-4-(4-chlorophenyl)-4,5-dihydropyridazin-3(2H)-one (CAS 344282-69-5) is a high-purity analytical reference standard with the molecular formula C16H12BrClN2O and a molecular weight of 363.64 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 6-(4-Bromophenyl)-4-(4-chlorophenyl)-4,5-dihydropyridazin-3(2H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
