Used in neuroscience research to study sigma-1 receptors, which play a role in neuroprotection, cellular stress response, and modulation of ion channels. It serves as a selective agonist for sigma-1 receptors, making it a valuable tool for investigating neurological conditions such as Alzheimer's, Parkinson's, and depression. Also utilized in studies related to pain management and addiction due to its influence on neurotransmitter systems. Its high selectivity allows researchers to isolate sigma-1 receptor functions without significant off-target effects.
