1-Bromo-3-chloro-5,5-dimethylhydantoin

1-Bromo-3-chloro-5,5-dimethylhydantoin, commonly known as BCDMH, is a halogenated hydantoin compound available under trade names including Agribrom, Halobrom, and Halogene. It carries no assigned E-code and is registered under CAS 32718-18-6 and EC 251-171-5.

BCDMH is used as a biocide in industrial and recreational water treatment, where it releases both bromine and chlorine upon contact with water to inactivate bacteria, algae, and biofilm-forming organisms. In agricultural applications, it functions as a disinfectant for irrigation systems and post-harvest wash water, controlling microbial contamination at the point of contact.

The compound is supplied in powder, granular, and briquette forms to suit different dosing systems and handling requirements. It falls under REACH regulation and suppliers should confirm compliance documentation accordingly. Buyers should request safety data sheets and confirm grade specifications prior to procurement.
