This chemical is primarily used in research and development as a selective antagonist for the NK1 receptor, which plays a significant role in neurokinin signaling pathways. Its application is crucial in studies focused on understanding and modulating pain, inflammation, and central nervous system disorders. Additionally, it serves as a valuable tool in pharmacological research to investigate the role of NK1 receptors in various physiological and pathological processes, aiding in the development of potential therapeutic agents targeting these pathways.
