Used primarily in pharmaceutical research as a potent and selective antagonist for serotonin 5-HT2A receptors. This activity makes it valuable in studying neurological pathways related to mood, perception, and cognition. It has been investigated for potential applications in treating psychiatric disorders such as schizophrenia, depression, and anxiety, particularly where serotonin signaling is disrupted. Due to its high affinity and selectivity, it is also employed as a radioligand in receptor binding assays to map 5-HT2A receptor distribution in the brain. Its structural properties support the development of novel CNS-active compounds with improved efficacy and reduced side effects.
