Used primarily in the synthesis of pharmaceuticals, particularly in the development of antipsychotic drugs. It serves as an intermediate in the production of phenothiazine derivatives, which are known for their therapeutic effects in treating mental health disorders such as schizophrenia and severe anxiety. Additionally, it finds application in research settings for studying the biochemical pathways and mechanisms of action of psychotropic medications. Its role in medicinal chemistry is crucial for creating compounds that modulate neurotransmitter activity in the brain.
