Used primarily as a monomer in the synthesis of specialty polymers and resins, 2,6-Dichlorostyrene contributes to improved thermal and oxidative stability in plastics. Its structure allows for the development of high-performance materials suitable for harsh environments, including electrical insulation and industrial coatings. It is also employed in the production of optical materials and as an intermediate in the manufacture of agrochemicals and pharmaceuticals. Due to the chlorine substituents, it enhances flame retardancy in polymer formulations, making it valuable in applications requiring reduced flammability.
