4,5-Dichlorophthalic acid (CAS: 2710-89-6) is a key chlorinated aromatic intermediate synthesized via direct chlorination of phthalic anhydride or oxidation of dichlorotoluene. Its molecular formula is C8H4Cl2O4, serving as a critical precursor for high-performance polymers and agrochemicals.
Store in sealed containers under dry conditions below 25°C to prevent hydrolysis. Personnel must wear chemical-resistant gloves and eye protection due to potential skin irritation and corrosive properties upon contact.
