Product Description

1 3-Dibromo-5 5-dimethylhydantoin CAS 77-48-5

DBDMH is an organic compound derived from the heterocycle called dimethylhydantoin. 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. Its action does not involve the use of hypochlorous acid.

production method
By 5,5-dimethylhydantoin obtained by bromination. The 5,5-dimethylhydantoin, sodium carbonate, sodium hydroxide, and water were mixed, and bromine was slowly added under cooling. After the addition, the mixture was poured into water, and the crystals that were filtered out after standing were crude. Then, the crude product was dissolved in acetone, decolorized and filtered, and the filtrate was poured into water to obtain white crystals, which were finished products.
Mainly used as bactericidal and algicide, it can effectively kill various bacteria, fungi, viruses, algae, hepatitis virus, Escherichia coli, Staphylococcus aureus, gonorrhea, cholera, Salmonella typhimurium, etc., and can be widely used in aquaculture. Effectively prevent and treat various bacterial and fungal diseases such as fish, clams, crabs, shrimps, frogs, and shellfish; and sterilize and sterilize industrial water, tap water, domestic sewage, and swimming pools. This product is a kind of special brominating agent. Compared with brominating agents such as N-bromoacetamide and N-bromosuccinimide, it has the advantages of high active bromine content, good storage stability, and economical use. It is widely used. Allyl and benzyl compounds in chemical and pharmaceutical industries and bromination on active aromatic rings are also used as disinfectants or sanitizers.
