Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block in the creation of bioactive molecules due to its piperazine core, which is commonly found in drugs with neurological and psychiatric applications. Its cyclobutylcarbonyl group enhances metabolic stability and influences receptor binding affinity, making it valuable in medicinal chemistry for optimizing drug candidates. Also utilized in research settings for structure-activity relationship studies.
