Description

Tetrabromophthalic Acid is a high-purity brominated aromatic acid derivative, serving as a critical intermediate in the synthesis of advanced flame retardants. Its high bromine content and reactive acid groups make it a valuable building block for creating effective and thermally stable additives. This compound is essential for manufacturers in the polymer, electronics, and construction material industries seeking to enhance the fire safety of their products.

Application

• Primary intermediate for the synthesis of brominated epoxy resins and polycarbonate oligomers used as reactive flame retardants.
• Key raw material in the production of tetrabromophthalic anhydride, a widely used additive flame retardant.
• Used in the manufacture of flame-retardant compounds for engineering plastics, including PBT, PET, and ABS.
• Application in printed circuit board (PCB) laminates to meet UL94 V-0 and other fire safety standards.
• Component in formulations for fire-resistant coatings and cables.
• Potential use as a chemical intermediate in the synthesis of dyes, pigments, and pharmaceutical agents.
