Molecular Formula:

C₅H₆N₂BrClO₂

Molecular Weight:

241.47

Structure Formula:

Properties:

1-Bromo-3-chloro-5,5-dimethylhydantoin is also called BCDMH, and Bromo chloro dimethyl hydantoin. BCDMH is white or off-white crystal powder, slightly dissolved in water and also dissoluble in many organic solvents.

Bromo chloro dimethyl hydantoin (BCDMH) has a chlorine odor. It is resolved at 160°C. When decomposed, it produces irritating toxic smoke. The solubility of BCDMH is 2g/L in water at 20 °C. The pH of the 1% aqueous solution is 2.88.

Bromo chloro dimethylhydantoin (BCDMH) is prone to moisture absorption. After moisture absorption, it is partially decomposed and reacted in water to generate hypobromite acid and hypochlorous acid.

BCDMH can be further processed as granular and tablet. It is stable when dry and easy to decompose when moistened.

Bromo chloro dimethylhydantoin are broad-spectrum halogen release products. It is used to control the growth of algae, slime, biofilm, bacterial and fungal populations in industrial water systems. BCDMH tablets contain bromo-chloro-dimethyl-hydantoin as the active ingredient, which slowly releases bromine and chlorine when placed in water.

Bromo chloro dimethylhydantoin is also an excellent source of both chlorine and bromine as it reacts slowly with water releasing hypochlorous acid and hypobromous acid. It is used as a chemical disinfectant for recreational water sanitation and drinking water purification.

Preparation:

BCDMH is prepared by bromination and chlorination of 5, 5-dimethylhaine.

Applications:

BCDMH is an effective oxidant oxidizer and disinfectant, including advantages of both Bromo and Chloro, with high stabilization, light odor, slow-release, and long efficiency. Bromo chloro dimethylhydantoin can be widely used in the below fields.

• Sterilization for swimming pools and tap water
• Sterilization for aquaculture
• Sterilization for industrial water
• Sterilization of the environment for hotels, hospitals and other public places.

90% of BCDMH products are used in swimming pools, heat pipes, and hot springs for sterilization and disinfection. The general usage is 0.5~3mg/L. Bromo chloro dimethylhydantoin (BCDMH) is used as a fungicide in industrial circulating cooling water and industrial wastewater treatment. It is 10~20 times more effective than chlorine in removing biofilm and preventing biofilm formation on the heat transfer surface.
