Used as an intermediate in the synthesis of central nervous system (CNS) pharmaceuticals, particularly antipsychotics and other neuroactive agents. It serves as a building block for compounds targeting neurotransmitter modulation, such as dopamine antagonists for treating psychiatric disorders. The phenolic hydroxyl and carbonyl groups enable versatile modifications in organic synthesis, while the 4-chlorobutyl chain facilitates nucleophilic substitutions to incorporate heterocyclic rings. Valuable in medicinal chemistry for developing new CNS drug candidates and exploring structure-activity relationships.
