Used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. It plays a key role in the production of certain antipsychotic and antidepressant drugs due to its structural compatibility with central nervous system agents. Also employed in the development of dyes and specialty polymers where aromatic amines are required for coupling reactions. Its pyrrolidinyl-aniline structure makes it valuable in medicinal chemistry for modifying bioavailability and receptor binding in drug candidates.
