Used primarily as an intermediate in the production of vinyl chloride monomer, which is essential for manufacturing polyvinyl chloride (PVC) plastics, resins, and packaging materials. Also serves as a solvent in industrial processes such as rubber and resin extraction, though this use has declined due to toxicity concerns. Historically used in leaded gasoline as a scavenger to remove lead deposits in engines, but this application has been phased out in most countries. Occasionally employed in fumigants and as a degreasing agent for metal parts. Its role is mostly confined to closed chemical synthesis processes due to environmental and health risks.
