DBNPA 2,2-dibromo-3-nitrilopropionamide CAS 10222-01-2 is a quick-kill biocide that easily hydrolyzes under both acidic and alkaline conditions. It is preferred for its instability in water as it quickly kills and then quickly degrades to form a number of products, depending on the conditions, including ammonia, bromide ions, dibromoacetonitrile, and dibromoacetic acid. DBNPA acts similar to the typical halogen biocides.

DBNPA is white crystalline powder, melting point, 122-125℃,PH value, 5--5.5. DBNPA  is soluble in common organic solvents (such as acetone,benzene, dimethylformamide, ethanol, polyethylene glycol, etc.),slightly soluble in water. Under acidic conditions, its aqueous solution is more stable. Raising the PH, heating or being exposured under UV and  fluorescent light can fasten its dissolving. DBNPA is used in a wide variety of applications. Some examples are in papermaking as a preservative in paper coating and slurries. It is also used as slime control on papermachines, and as a biocide in hydraulic fracturing wells and in cooling water.
