Description

Dibromostyrene CAS NO 31780-26-4 is a halogenated styrene derivative, a versatile brominated monomer and chemical intermediate. Its primary value lies in its ability to introduce bromine functionality and a reactive vinyl group into polymer chains and organic molecules, imparting flame retardancy and enabling further chemical modifications. This compound is essential for R&D chemists and industrial manufacturers in the polymer, specialty chemical, and pharmaceutical sectors seeking to develop advanced materials with enhanced properties.

Application

• As a key monomer for synthesizing flame-retardant polymers and copolymers, particularly for engineering plastics and coatings.
• As a reactive intermediate in organic synthesis for pharmaceuticals and agrochemicals.
• In the production of specialty adhesives and sealants where bromine content is required for specific performance characteristics.
• For research and development of novel polymeric materials with tailored thermal and chemical resistance.
• As a cross-linking agent or modifier in polymer systems to alter physical properties.
• In the synthesis of liquid crystals and other advanced electronic materials.
