Used in scientific research to study the role of the orexin receptor system in regulating sleep-wake cycles, arousal, and appetite. It acts as a potent and selective antagonist for the orexin OX1 receptor, making it a valuable tool for investigating neurological pathways involved in insomnia, narcolepsy, and other sleep disorders. Researchers also explore its potential in understanding addiction and stress-related behaviors due to the orexin system’s involvement in reward processing and emotional regulation. Not intended for clinical use or human consumption.
