Store 4-Bromo Phthalic anhydride (CAS 86-90-8, white to pale yellow crystalline powder, mp 122-125℃, density 1.89g/cm³, bp 370℃, purity ≥98%, moisture-sensitive) at 5–25℃ in sealed amber glass/HDPE drums in a cool, dry, well-ventilated area, away from open fire, strong oxidants and water. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent corrosive irritation. Reseal tightly post-use; dispose of waste per local aromatic anhydride regulations (neutralize before discharge).

4-Bromo Phthalic anhydride CAS 86-90-8 is an industrial brominated aromatic anhydride with corrosivity, strictly forbidden to direct skin contact or ingestion; contact with water causes hydrolysis to corrosive acid.

In regulated use, 4-Bromo Phthalic anhydride CAS 86-90-8 features high reactivity in ring-opening and amidation reactions, good solubility in polar organic solvents, excellent thermal stability during processing, and the bromine substituent enables precise functionalization for high-performance material synthesis with high yield.
