2.2-Dibromo-3-Nitrilopropion Amide (DBNPA) is a broad-spectrum and high-efficiency industrial fungicide. It could rapidly penetrate the cell membrane of microorganisms and acton certain protein groups to stop normal redox cells and cause cell death. Atthe same time, its branches can also selectively brominate or oxidize specificenzyme metabolites of microorganisms, eventually leading to the death ofmicroorganisms. This product has a good peeling performance, no foam when used,liquid products and water can be any mutual miscibility, low toxicity.  Widely used for water treatment agents, bactericidalalgicide, papermaking  circulating cooling water system.

As an efficient industrial fungicide; It’s used for water treatment agents, bactericidal algicide, papermaking and pharmaceutical intermediates to prevent bacteria and algae in the field of papermaking, industrial circulating cooling water, lubricants for metal processing, Wood, paint and plywood in the growth and reproduction. It also could be used as slime control agent, widely used in paper mill pulp and circulating cooling water system.


The aqueous solution is relatively stableunder acidic conditions and is easily hydrolyzed under alkaline conditions.Raising the pH, heating, and irradiating with ultraviolet or fluorescent lightcan greatly increase the dissolution rate.
