Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It plays a role in the production of compounds with potential neuroprotective and cognitive-enhancing properties. Also utilized in agrochemical research for the design of novel pesticides due to its ability to interact with insect nervous systems. Its nitrile and chloropyridazine groups make it a valuable building block in medicinal chemistry for constructing biologically active molecules.
