DBNPA 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.
Properties:
White crystals. Melting point of 125℃, it can soluble in common organic solvents (such as acetone, benzene, dimethylformamide, ethanol, polyethylene glycol, etc. Slightly soluble in water (25 ℃, 100g water dissolved 1.5g). Its aqueous solution is more stable under acidic conditions, and easy hydrolysis in alkaline conditions. Increasing the pH value, heating with ultraviolet light or fluorescent light, can make its dissolution rate greatly accelerated. Easy to be reductant, such as hydrogen bromide and bromine into non-toxic cyanide acetamide, the sterilization rate greatly reduced. When its pH value increase from 6.7 to 9.7, the half-life will change from 37.0h into 0.11h.

Applications:
1). It is used as anti-microbial agent, controlling bacterial, fungal and algal growth in industrial water systems like cooling towers, pulp and paper mill process water, oil-recovery systems and air-conditioning systems.
2). DBNPA has good peeling performance, no foam, and its liquid products and water can be dissolved at any ratio.
3). It can quickly penetrate the cell membrane of microorganisms and act on a certain protein group to stop the normal redox of cells and cause cell death.
