Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor ligands and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in creating compounds with neurological activity. Also employed in agrochemical research for developing new pesticides due to the presence of electron-withdrawing groups that enhance reactivity and binding properties. The nitro and chloro substituents enable sequential substitution reactions, facilitating the construction of complex heterocyclic systems in medicinal chemistry.
