Used as a potent and selective antagonist for the orexin OX2 receptor (OX2R), this compound is primarily applied in research related to sleep disorders, particularly narcolepsy. It helps in studying the role of orexin signaling in regulating wakefulness and sleep cycles.

Due to its ability to cross the blood-brain barrier and selectively modulate OX2R activity, it serves as a valuable tool in developing potential therapeutics for insomnia and other central nervous system disorders involving hypersomnolence.

Its structure allows for high affinity binding, making it useful in pharmacological assays and in vivo studies aimed at understanding sleep-wake regulation.
