4-Methoxybenzoyl chloride Usage And Synthesis
Chemical Properties colourless liquid
Usage Intermediates of Liquid Crystals
Usage 4-Methoxybenzoyl Chloride is used in the synthesis of stilbene and dihydrostilbene derivatives as potential anti-cancer agents. It is also used in the synthesis of coumarin dimers with potential HIV-1 activity.
General Description An amber-colored crystalline solid. Melting point 72°F. Corrosive to metals and skin. Vapors may cause serious burns to the eyes.
Air & Water Reactions Fumes in air. Reacts exothermically with water (including moisture in air or soil) to form hydrochloric acid and insoluble anisic acid [Merck 11th ed. 1989].
Reactivity Profile ANISOYL CHLORIDE reacts exothermically with bases, including amines. Incompatible with water, strong oxidizing agents, alcohols. Sealed containers held at room temperature may explode, due to slow decomposition that builds up pressure. This situation is more dangerous with heat. May react vigorously or explosively with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
Health Hazard Vapor irritates mucous membranes. Contact of liquid with eyes or skin causes severe irritation. Ingestion causes severe irritation of mouth and stomach.
Fire Hazard Special Hazards of Combustion Products: Irritating hydrogen chloride fumes may be formed.
