1,2-Dibromoethylene, a mixture of cis- and trans-isomers, is primarily used in organic synthesis and as an intermediate in the production of various chemicals. It serves as a building block in the manufacture of flame retardants, where its bromine content enhances fire resistance in materials like plastics, textiles, and polymers. Additionally, it is utilized in the synthesis of pharmaceuticals and agrochemicals, including pesticides and fungicides, contributing to the development of active ingredients for drugs and crop protection products. Its high reactivity also makes it valuable in research laboratories for studying chemical reactions and developing new compounds.
