Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antidepressants and psychoactive drugs. It plays a key role in the preparation of substituted amphetamines and hallucinogenic compounds due to its structural similarity to neurotransmitters. Also utilized in research settings for developing novel organic molecules and in the manufacture of specialty chemicals for analytical reagents. Its reactivity makes it valuable in coupling reactions for building complex aromatic amines.
