Used primarily as a solvent in the production of vinyl chloride, which is a key precursor for PVC manufacturing. It is also employed in the synthesis of other chemicals, such as ethyleneamines and ethylenediamine, which are used in various industrial applications. In the past, it was utilized as a degreaser and in the extraction of oils and fats, though its use in these areas has declined due to health and environmental concerns. Additionally, it serves as a fumigant for stored grains and soil, but this application is increasingly restricted. Its role as an intermediate in chemical reactions remains significant in industrial processes.
