1,1,2-Trichloroethane is primarily used as a solvent in various industrial applications. It is effective in dissolving oils, fats, resins, and waxes, making it suitable for use in cleaning and degreasing metal parts and electronic components. Additionally, it has been utilized in the formulation of adhesives and coatings, where its solvent properties help in achieving the desired consistency and performance. In the past, it was also employed as an intermediate in the production of other chemicals, including vinylidene chloride. However, its use has declined due to environmental and health concerns, leading to stricter regulations and the adoption of safer alternatives.
