CAS 632-79-1

Tetrabromophthalic anhydride

Description:

Tetrabromophthalic anhydride, with the CAS number 632-79-1, is a chemical compound characterized by its high bromine content, which imparts flame-retardant properties. It is derived from phthalic anhydride, where four hydrogen atoms are replaced by bromine atoms. This compound typically appears as a white to light yellow crystalline solid and is known for its reactivity, particularly in the presence of nucleophiles, due to the electrophilic nature of the anhydride functional group. Tetrabromophthalic anhydride is primarily used in the production of flame-retardant materials, including resins and polymers, and is also utilized in the synthesis of various chemical intermediates. Its high thermal stability and ability to enhance the fire resistance of materials make it valuable in industries such as electronics, textiles, and construction. However, handling this compound requires caution due to its potential health hazards, including skin and respiratory irritation. Proper safety measures should be observed when working with tetrabromophthalic anhydride to mitigate any risks associated with exposure.
