Description

Benzene, Ethenyl-, Ar-Bromo Derivs. CAS NO 125904-11-2 is a specialized class of brominated styrene derivatives, characterized by the introduction of bromine atoms onto the aromatic ring of the vinylbenzene structure. These compounds are of significant industrial importance as versatile intermediates and monomers for the synthesis of advanced polymers and fine chemicals. They are primarily utilized by R&D laboratories and production facilities in the polymer, pharmaceutical, and specialty chemical sectors seeking to incorporate flame-retardant properties or specific reactive sites into their final products.

Application

• Flame-Retardant Polymer Additive: Acts as a reactive comonomer or additive in the production of polystyrene, ABS, and other engineering plastics to enhance fire resistance.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Specialty Chemical Synthesis: Used in organic synthesis for cross-coupling reactions (e.g., Suzuki, Heck) to create complex aromatic compounds for agrochemicals and dyes.
• Advanced Material Research: Employed in R&D for developing novel polymers with tailored optical, electronic, or mechanical properties.
• Liquid Crystal & OLED Materials: Functions as a precursor in the manufacture of brominated aromatic cores for electronic display materials.
