Used primarily in research as a potent and selective antagonist for the 5-HT6 receptor, this compound plays a key role in neuroscience studies focused on cognitive function, memory, and neurodegenerative diseases such as Alzheimer's. It serves as a pharmacological tool to help elucidate the role of serotonin signaling in the central nervous system. Due to its ability to cross the blood-brain barrier effectively, it is valuable in in vivo models for assessing behavioral and cognitive effects of 5-HT6 receptor modulation. It has also been explored in the development of potential therapeutics for psychiatric disorders including schizophrenia and depression, where serotonin pathways are implicated.
