CAS.2789616-13-1 4,6-Dibromo-2-fluoro-1,3-benzenediacetonitrile

Based on its structure, it can serve as a key building unit for synthesizing high-performance polymers (resins). The introduced cyano and bromine atoms can significantly enhance the heat resistance, mechanical strength, and flame retardancy of these traditional high-performance plastics. Additionally, the cyano group can hydrolyze into carboxyl groups, which then undergo polycondensation with diamine monomers to prepare polyimide. Fluorine- and bromine-containing polyimides may exhibit higher transparency, lower dielectric constant, and excellent flame retardant properties, making them suitable for high-end electronic applications.
