Used primarily as an intermediate in organic synthesis, especially in the preparation of pharmaceuticals and biologically active compounds. Its structure, featuring a piperidine ring linked to a nitrophenyl group, makes it valuable in the development of central nervous system agents, including analgesics and neuroactive drugs. The nitro group allows for further functionalization, such as reduction to an amine, enabling the creation of more complex molecules. It is also employed in the synthesis of certain dyes and specialty chemicals where aromatic nitro compounds are required.
