DBNPA (2,2-dibromo-2-cyanoacetamide), with the chemical formula $$C_{3}H_{2}Br_{2}N_{2}O$$ and a molecular weight of 241.869, is a white crystalline solid. It has a density of 2.5 ± 0.1 g/cm³, a melting point in the range of 122 - 125 °C (lit.), and a boiling point of 221.5 ± 40.0 °C at 760 mmHg. Slightly soluble in water (1.5 g/100 mL at 25°C), it is soluble in organic solvents like methanol, acetone, and ethanol.his compound is a highly effective biocide, widely employed in various industries. In industrial water treatment, it plays a crucial role in preventing the growth of bacteria, fungi, and algae in cooling water systems, which helps to maintain the efficiency of heat exchangers and pipelines, reducing the risk of corrosion and blockage. In the coatings industry, DBNPA is added to prevent the degradation of coatings by microorganisms, ensuring the durability and appearance of the coated surfaces. It is also used in personal care products, such as shampoos and lotions
In industrial water systems like cooling towers and circulating water networks, microbial growth—including bacteria, algae, and slime—poses significant risks to efficiency and equipment integrity. DBNPA (2,2-Dibromo-3-nitrilopropionamide) has emerged as a pivotal biocide for rapid and effective control of these contaminants. This article explores how DBNPA functions, its advantages, and best practices for its application in maintaining clean, efficient water systems.
