Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antidepressants and antipsychotic drugs. It serves as a building block in organic reactions where the amino and hydroxyl groups allow for further functionalization. Commonly employed in the development of serotonin receptor modulators. Also utilized in the preparation of dyes and fluorescent compounds due to its aromatic amine structure. Its chloro-substituted phenyl ring enhances reactivity in cross-coupling reactions, making it valuable in medicinal chemistry research.
