Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure allows for the introduction of azepane moieties into larger molecules, which can enhance binding affinity to certain receptors. Commonly employed in the preparation of selective serotonin reuptake inhibitors and other neuroactive drugs. Also utilized in research settings for the construction of novel bioactive molecules due to its reactive benzyl chloride group and flexible ether linkage.
