Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Computed Properties of C10H6Cl2N2O
Substituted 5-hydrazinopyridazin-3(2H)-ones, e.g., 4-chloro-2-(3-trifluoromethylphenyl)-5-(1-methylhydrazino)-pyridazin-3(2H)-one or 4-chloro-2-(2-fluoro-5-trifluoromethylphenyl)-5-(1-methylhydrazino)-pyridazin-3(2H)-one, are prepared by treating halogenated pyridazin-3-(2H)-ones with hydrazine and substituted hydrazines and are useful as central nervous system depressants and sleep inducers.
