Used in scientific research to study the mechanisms of erectile function and sexual arousal, particularly through selective activation of dopamine D4 receptors. It has been investigated for its potential in treating sexual dysfunction, including erectile dysfunction and hypoactive sexual desire disorder. Due to its receptor specificity, it serves as a tool compound in neuropharmacology to explore dopaminergic pathways involved in motivation, reward, and sexual behavior. Not intended for clinical use in humans and is restricted to laboratory and preclinical studies.
