1,2-Bis(2-cyanoethoxy)ethane, also known as bis(2-cyanoethoxy)ethane, is a chemical compound with the molecular formula C8H12N2O2. It is a diester derivative containing two cyanoethoxy groups attached to a central ethane backbone. This compound is primarily used as a crosslinking agent in the synthesis of polymeric materials, particularly in the production of polyurethanes and epoxy resins. Its bifunctional nature allows it to participate in the formation of covalent bonds between polymer chains, enhancing the mechanical strength, durability, and thermal properties of the resulting materials. Additionally, 1,2-Bis(2-cyanoethoxy)ethane is employed in the preparation of specialty polymers and composites with tailored properties for applications in adhesives, coatings, and structural materials.
