Flupentixol dihydrochloride is a synthetic thioxanthene derivative and a specialty chemical used primarily in pharmacological and biochemical research as an antipsychotic agent. It acts as a dopamine D2 receptor antagonist, aiding studies on schizophrenia, psychosis, and related psychiatric disorders by modulating neurotransmitter activity. This high-purity reagent (≥99%) is also investigated for its potential in depression models due to mood-stabilizing effects. It is supplied for laboratory use only, not for human or veterinary administration. Key specifications include white to off-white solid appearance, conformity to IR and NMR structures, and purity of 98.5-100%.
