Industrial Uses

1. Performance Chemicals

  • Intermediate in Brominated and Chlorinated Derivatives: DMH is widely used as a precursor to synthesize halogenated compounds such as 1,3-Dichloro-5,5-dimethylhydantoin (DCDMH) and 1,3-Dibromo-5,5-dimethylhydantoin (DBDMH). These are stable sources of halogens for disinfection and oxidation.
  • Synthesis of Disinfectants and Biocides: Used in the preparation of active ingredients for disinfectant tablets, powders, and slow-release formulations for water treatment or sanitation.

2. Water Treatment 

  • Precursor for Halogen Donors: DMH is converted into halogenated hydantoins that act as controlled-release chlorine or bromine agents in cooling towers, swimming pools, and wastewater systems.
  • Stabilizer for Active Halogen Compounds: In some formulations, DMH acts as a stabilizing base molecule to prevent rapid degradation of active bromine/chlorine compounds during storage or use.

3. Pharmaceuticals

  • Intermediate for Drug Synthesis: DMH is used in the development of heterocyclic drug intermediates, especially in research focused on antimicrobial, anticonvulsant, and antitumor agents.
  • Precursor for Bioactive Molecules: Utilized in synthesizing substituted hydantoins which are studied for their biological activity, especially in neurology and antimicrobial drug design.

4. Polymers & Resins

  • Cross-linking Agent in Resins: DMH derivatives are sometimes used to modify epoxy or acrylic resins to improve hardness, thermal stability, and water resistance.
  • Intermediate in UV-Curable Polymers: Certain DMH derivatives contribute to the development of UV-sensitive polymers for coatings, adhesives, and printing inks.

5. Agrochemicals

  • Intermediate in AgroPerformance Chemicals: DMH is used to create halogenated derivatives employed in fungicide or pesticide formulations.
  • Carrier in Slow-Release Formulations: Modified hydantoin structures are used to design slow-release agrochemical carriers, which release active ingredients over time in soil or water.
