Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly those targeting the central nervous system. Shows utility in developing serotonin receptor modulators, which are relevant for treating anxiety, depression, and other neurological disorders. Also employed as a building block in the preparation of novel piperazine derivatives for structure-activity relationship studies. Its methoxyphenyl group contributes to enhanced lipophilicity and receptor binding affinity, making it valuable in medicinal chemistry for optimizing drug candidates.
