99% Purity White Crystal Powder 1,3-Dibromo-5,5-dimethylhydantoin DBDMH as Industrial Brominating Agent and Disinfectant

Top Fine high-quality white crystal powder 1,3-Dibromo-5,5-dimethylhydantoin (99%, CAS 77-48-5) is a versatile industrial brominating agent and antiseptic disinfectant. It is a highly effective brominating agent that offers significant advantages over alternatives such as N-bromoacetamide and N-bromosuccinimide, including a high active bromine content, excellent storage stability, and economical application.

Due to these properties, it is widely used across the chemical and pharmaceutical industries — for the bromination of allyl and benzyl compounds and aromatic rings, the addition reaction of bromine to double bonds and hydrogen bromide, and the selective oxidation of secondary alcohols. In addition, it serves as an efficient and safe disinfectant with strong efficacy against fungi, bacteria, and viruses, as well as against adverse algae in water.

It is suitable for the prevention and treatment of numerous diseases in aquaculture affecting fish, shrimp, frogs, and turtles, as well as for swimming pool disinfection, fruit preservation, algae control in industrial recycled water, and routine daily disinfection. For example, experts on the Beijing SARS prevention and control working panel proposed using a 1,3-Dibromo-5,5-dimethylhydantoin solution with an effective bromine concentration of 500–1000 mg/L for spraying, mopping, and cleaning, with a disinfection contact time of 10–15 minutes to help prevent SARS.

• Drinking water purification and recreational water treatment.
• Bleaching agent for pulp and paper mills.
• Treatment of industrial and commercial water cooling systems.
• Efficient and selective oxidation of thiols to disulfides, both in solution and under solvent-free conditions.
