Used in pharmaceutical research as an intermediate in the synthesis of bioactive molecules, particularly in the development of central nervous system agents. Shows potential in the design of serotonin receptor modulators due to structural similarity to known neuroactive compounds. Also explored in the preparation of novel heterocyclic derivatives for antimicrobial and anti-inflammatory studies. Its nitroaromatic-piperazinone framework makes it valuable in medicinal chemistry for structure-activity relationship (SAR) exploration.
