Description

1,3-Dibromo-5,5-Dimethylhydantoin (DBDMH) is a versatile and highly effective brominating and oxidizing agent widely used in organic synthesis and water treatment. Its controlled release of active bromine makes it a powerful yet manageable alternative to hazardous elemental bromine. This compound is essential for manufacturers and researchers in the pharmaceutical, agrochemical, and industrial biocidal sectors seeking efficient halogenation and disinfection solutions.

Application

• Organic Synthesis Intermediate: A key reagent for bromination and oxidation reactions in the production of active pharmaceutical ingredients (APIs) and fine chemicals.
• Industrial Water Treatment: Used as a powerful biocide and algicide in cooling towers, recreational water, and industrial process water systems.
• Agrochemical Manufacturing: Serves as a brominating agent in the synthesis of certain pesticides and herbicides.
• Polymer Chemistry: Employed as a flame retardant precursor and a modifier in polymer synthesis.
• Laboratory Reagent: Utilized in research and development for selective bromination under mild conditions.
• Pulp & Paper Industry: Acts as a slimicide and disinfectant in process water to control microbial growth.

Quality Control

Our 1,3-Dibromo-5,5-Dimethylhydantoin is manufactured under a strict quality management system. Every batch is tested to ensure it meets high-purity standards for consistent performance in sensitive applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee supply reliability and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere for long-term stability. Keep container tightly sealed when not in use to minimize moisture absorption and decomposition.
