CAS 77-48-5 Active Pharmaceutical Ingredients 1,3- Dibromo -5,5- dimethylhydantoin



  • Overview of Active Pharmaceutical Ingredients 1,3-Dibromo-5,5-dimethylhydantoin:


1. 1, 3-Dibromo-5, 5-dimethylhydantoin is primarily used as an industrial brominating agent and antiseptic disinfectant. It is a very useful kind of brominating agent. Compared with brominating agent such as N-bromoacetamide, N-bromosuccinimide, etc. it has a lot of advantages including high content of active bromine, excellent storage stability, and economic application.


2. Therefore, it is widely applied to chemical and pharmaceutical industry such as being used for the bromination of allyl and benzyl compounds as well as aromatic ring, the addition reaction of the bromine in double bond and hydrogen bromide as well as the selective oxidation of secondary alcohols.


3. In addition, it is also a kind of efficient and safe disinfectant with a strong efficacy in killing fungi, bacteria and viruses as well as in killing the adverse algae in the water.


4. It can be applied to the prevention and treatment of many kinds of diseases in aquaculture related to fish, shrimp, frogs and turtles as well as the disinfection of swimming pool, fruit preservation and algae killing via industrial recycled water algae and daily disinfection.


  • Application of  Active Pharmaceutical Ingredients 1,3-Dibromo-5,5-dimethylhydantoin:


1. DBDMH is an important chemical product and has been widely applied in chemical, pharmaceutical and agricultural industries with various kinds of advantages including excellent stability, high content of bromine and high reactive activity.


2. Currently, the combined formulation between DBDMH and other halogenated hydantoin for application has become a hotspot in recent years such as the combined application of BCDMH and DBDMH as well as the combined application of DCDMH and DBDMH. For the combined formulation of DBDMH and other halogenated hydantoin, one critical factor is the ratio between effective chlorine and effective bromine. For example, at pH 7.1, compound formulation with the same dose of BCDMH and DBDMH has a significantly higher bactericidal efficacy than DBDMH alone or BCDMH alone.


3. Many domestic and foreign experts believe that the most significant oxidizing biocide is the compound halogenated compound formulation combining BCDMH and DBDMH. In agriculture, DBDMH is mainly used for aquaculture including pond disinfection, prevention of water disinfection, disease treatment, etc., and is not affected by water quality, salinity, pH, temperature, and other organic compounds during usage.


4. In addition, there has been already cases in which people has applied DBDMH as high-efficiency and low-toxicity disinfectant for combined formulation with stearic acid monoglyceride and Tween-80 and applied to the surface of the orange for preventing mold and preservation, and has already achieved excellent results.


5. We can expect that this preservative can also be used for storage and preservation of other fruits and vegetables. Therefore, with the continuous development of chemical and pharmaceutical industry and increasing people's living standards, it is expected that the application range and demand of DBDMH will increase greatly.


  • Physical and Chemical Property of Active Pharmaceutical Ingredients 1,3-Dibromo-5,5-dimethylhydantoin:


1, 3-Dibromo-5, 5-dimethylhydantoin has the English abbreviation be DBDMH with pure product being white solid and the mp being 196 ~ 198 ℃. The industrial products appear as a pale yellow solid with a mp of 194 ~ 197 ℃;

It is soluble in chloroform, ethanol, acetone and other organic solvents, slightly soluble in water with 1 L water being able to dissolve 2.2 g of DBDMH at 20℃ with the pH of 0.1% aqueous solution being 2.6; It is prone to be subject to decomposition in strong acid or alkali;


It is stable when dry and is easy to absorb moisture with partially hydrolysis after moisture absorption; it has a slight pungent odor with the active bromine content being 54% to 55%.


  • Sterilization Mechanism of Active Pharmaceutical Ingredients 1,3-Dibromo-5,5-dimethylhydantoin:


DBDMH, upon hydrolysis in water, can mainly form hypobromous acid and can release bromine in the form of hypobromous acid. DBDMH, due to able to release bromine in a high reaction rate, can continuously release Br- ions in the water, further playing a bactericidal effect.


However, other kinds of halogenated hydantoin, such as 1, 3-Dibromo-5, 5-dimethylhydantoin or bromochlorohydantoin, release the chlorine in a very slow rate, leading to that the time for reaching the peak of sterilization in the water is lagging behind, therefore, DBDMH usually has a higher efficiency than other kind of halogenated hydantoin at relatively rapid bactericidal conditions.
