Description

Droperidol (CAS: 548-73-2) is a potent butyrophenone-class antipsychotic and antiemetic agent with the molecular formula C₂₂H₂₂FN₃O₂. Its IUPAC name is 3-[1-[4-(4-fluorophenyl)-4-oxobutyl]-3,6-dihydro-2H-pyridin-4-yl]-1H-benzimidazol-2-one. This high-purity compound is supplied as a fine white to off-white crystalline powder, suitable for research and pharmaceutical development. Droperidol exhibits strong dopamine D₂ receptor antagonism, with additional activity at α₁-adrenergic and serotonin receptors. It is highly soluble in organic solvents like ethanol and DMSO, but has limited aqueous solubility. Store at 2-8°C in a tightly sealed container protected from light and moisture. Offered in various quantities with ≥98% HPLC purity, accompanied by comprehensive analytical data (MS, NMR, HPLC).
