Products Description of 2,2-Dibromo-2-cyanoacetamide CAS#10222-01-2
2,2-Dibromo-2-cyanoacetamide, also known as DBNPA, has CAS#10222-01-2 with molecular formula C3H2Br2N2O. This product is a fast-acting broad-spectrum biocide. It is white to pale yellow crystalline powder with a melting point of 125℃. It exhibits good solubility in conventional organic solvents including acetone, benzene, dimethylformamide, ethanol and polyethylene glycol, while showing poor solubility in water.
This compound maintains relatively stable properties in acidic aqueous solutions, yet it is susceptible to hydrolysis under alkaline conditions. Elevated pH values, heating conditions, ultraviolet radiation and fluorescent light exposure can effectively accelerate its hydrolysis and dissolution process.
It can undergo debromination reactions in the presence of reducing agents such as hydrogen sulfide, generating non toxic cyanoacetamide and substantially losing its sterilizing performance. Its stability varies greatly with pH changes. When the pH level rises from 6.7 to 9.7, its half life drops sharply from 37.0 hours to 0.11 hours.

Product Application of 2,2-Dibromo-2-cyanoacetamide CAS#10222-01-2
2,2-Dibromo-2-cyanoacetamide is a high efficiency and broad spectrum biocide. It penetrates microbial cell membranes quickly and binds with specific cellular protein groups to block normal redox metabolism, which eventually leads to microbial inactivation and death. It also inhibits microbial activity through selective bromination and oxidation of key enzymatic metabolites inside microbial cells.
This compound serves as a professional bactericide and algaecide for industrial water and material protection scenarios. It effectively suppresses the reproduction of bacteria and algae in paper making water systems, industrial cooling water, air conditioning circulating water, metalworking lubricants, water based emulsions, pulp, wood, plywood, coatings and fiber materials. A concentration of 15 ppm 20% DBNPA achieves stable and efficient microbial control.
In addition to sterilization and algae removal, it can degrade accumulated biological sludge on equipment fillers and recover the heat exchange and evaporation efficiency of cooling tower systems.
