Guran, Cornelia Jitaru Ioana et al. published their research in Revue Roumaine de Chimie in 1994 | CAS: 2166-13-4

6-(4-Chlorophenyl)pyridazin-3(2H)-one (cas: 2166-13-4) belongs to pyridazine derivatives. Pyridazines are rare in nature, possibly reflecting the scarcity of naturally occurring hydrazines, common building blocks for the synthesis of these heterocycles. In the past decade, X-ray data were reported with regard to the characterization and structural elucidation of a number of pyridazine-metal complexes, including pyridazine ligands with zinc, nickel, copper, cadmium and ruthenium.Recommanded Product: 6-(4-Chlorophenyl)pyridazin-3(2H)-one

Chromium(III) complex thiocyanates with pyridazone derivatives was written by Guran, Cornelia Jitaru Ioana;Jitaru, Ioana;Ciocoiu, Ioana. And the article was included in Revue Roumaine de Chimie in 1994.Recommanded Product: 6-(4-Chlorophenyl)pyridazin-3(2H)-one This article mentions the following:

K[CrL2(NCS)4] (L = p-chlorophenylpyridazone, p-bromophenylpyridazone and p-tolylpyridazone) were prepared and characterized. The compounds are characterized by elemental chem. anal., measurements of elec. conductivity and electronic, IR and x-ray spectra. In the experiment, the researchers used many compounds, for example, 6-(4-Chlorophenyl)pyridazin-3(2H)-one (cas: 2166-13-4Recommanded Product: 6-(4-Chlorophenyl)pyridazin-3(2H)-one).
