1-Bromo-3-chloro-5,5-dimethylhydantoin丨CAS 16079-88-2

1-Bromo-3-chloro-5,5-dimethylhydantoin is primarily used as a biocidal agent in industrial water treatment systems. It is commonly applied in cooling towers, swimming pools, spas, and circulating water systems to control bacteria, algae, and fungi. In aquaculture and fisheries, it is used to maintain hygienic water conditions by reducing microbial contamination. The compound is also utilized in pulp and paper processing, textile manufacturing, and oilfield water treatment to prevent biofouling and microbial growth. In addition, BCDMH is used in sanitation formulations for cleaning equipment and surfaces in food processing facilities and industrial environments. Its stable solid form allows it to be formulated into tablets, granules, or slow-dissolving blocks for controlled disinfection over time.

One of the main advantages of 1-bromo-3-chloro-5,5-dimethylhydantoin is its ability to release both bromine and chlorine disinfecting agents gradually, providing strong and long-lasting antimicrobial activity. Bromine remains effective over a wider pH range compared with chlorine alone, making the compound suitable for diverse water treatment conditions. The hydantoin ring stabilizes the halogens, allowing safer storage and controlled release during use. BCDMH is effective at relatively low concentrations and demonstrates strong activity against bacteria, algae, and other microorganisms. Its solid form improves handling convenience and reduces transportation risks compared with liquid disinfectants. Additionally, the compound supports sustained microbial control in recirculating water systems, reducing the need for frequent chemical dosing.
