Dopamine stabilizer; lacks high affinity for various neuroreceptors in vitro (Ki values are 447 and 1305 nM for D2 and D3 receptors respectively and > 1 μM for other targets). Exhibits high D2 receptor occupancy in vivo; highly active on dopamine synthesis and turnover. Induces stabilizing effects on psychomotor function in behavioral tests without inducing hypolocomotion or catalepsy. Purity 98%. MW (observed): 317.87
