DBDMH (also known as 1,3-Dibromo-5,5-Dimethylhydantoin) is an organic compound derived from the heterocycle called dimethyl hydantoin. This white crystalline compound with a slight bromine odor is widely used as a disinfectant used for drinking water purification, recreational water treatment, as a bleaching agent in pulp and paper mills, and for treating industrial/commercial water cooling systems. [1] Its action does not involve the use of hypochlorous acid.
1,3-Dibromo-5,5-Dimethylhydantoin is a source of bromine, which is equivalent to hypobromous acid (HOBr).
(Where H2X is 5,5-dimethylhydantoin)
With a pKa of 8.6, hypobromous acid partially dissociates in water:
Hypobromous acid serves as a source of "Br+," which produces bromide ions in the process of disinfection:
The resulting bromide ions can then undergo oxidation to hypobromous acid in the presence of an oxidizer of sufficient strength e.g. ozone, hypochlorous acid, potassium mono persulfate. This reoxidation process is commonly called "activation" of the bromide ion:
