Description

1,3-Dibromo-5-Ethyl-5-Methylhydantoin is a highly effective halogenated hydantoin derivative, serving as a powerful and stable source of active bromine. This compound is valued for its controlled-release properties and broad-spectrum biocidal efficacy, making it a critical component in demanding water treatment and disinfection applications. It is primarily sought by professionals in the industrial water treatment, pulp & paper, and oilfield industries for its reliability and performance in challenging conditions.

Application

• Industrial Cooling Water Treatment: Acts as a potent biocide and slimicide in recirculating cooling towers and systems to control microbial growth, biofilm, and Legionella.
• Pulp & Paper Mill Process Water: Used for microbial control in white water systems to prevent spoilage, slime formation, and product defects.
• Oilfield Water Systems: Employed for disinfection and bacterial control in injection water, frac water, and produced water to prevent souring and corrosion.
• Swimming Pool & Spa Sanitation: Serves as a stabilized bromine donor for sanitizing recreational water, offering an alternative to chlorine-based products.
• Membrane Biocide: Protects reverse osmosis (RO) and ultrafiltration (UF) membranes from biofouling, ensuring system efficiency and longevity.
• Chemical Synthesis Intermediate: Utilized in organic synthesis as a brominating agent for the introduction of bromine atoms into target molecules.
