Used primarily in research settings as a reference compound for pharmacological studies, particularly in neuroscience and behavioral research. It acts as a potent antagonist at certain neurotransmitter receptors, making it valuable for studying receptor function and signaling pathways. Commonly employed in in vitro assays to investigate receptor binding affinity and selectivity. Due to its structural properties, it also serves as a building block in the synthesis of more complex molecules for drug development. Not intended for therapeutic use or human consumption.
