1. A colorless crystalline chemical compound (C₂Cl₆) used historically as a fumigant, solvent, and in various industrial applications, now largely restricted due to environmental and health concerns.
Usage: chemistry; technical; regulated substance in many countries

Examples

• Hexachloroethane was once widely used as a grain fumigant before stricter environmental regulations were implemented.
• The chemical compound hexachloroethane has a high melting point and low solubility in water.
• Industrial workers handling hexachloroethane must follow strict safety protocols due to its toxicity.
• Hexachloroethane production has declined significantly in developed nations over the past two decades.
• The persistence of hexachloroethane in the environment has made it a subject of ongoing scientific study.
