Used primarily in neuroscience research as a potent and selective non-competitive antagonist of the NMDA receptor. It is widely employed to study glutamatergic system dysfunction, particularly in models of neurodegenerative diseases, excitotoxicity, and schizophrenia. Due to its ability to induce behavioral and neurochemical changes resembling psychosis, it is used in animal models to investigate antipsychotic drugs and cognitive impairments. Also utilized in studies exploring synaptic plasticity, learning, and memory processes. Its high potency requires careful dosing in experimental settings.
