2,2-Dibromo-2-cyanoacetamide (DBNPA) CAS NO. 10222-01-2 CODE DBNPA Molecular formula C3H2Br2N2O Molecular weight 242 Use It is a broad-spectrum and high-efficiency industrial bactericide, used to prevent the growth and reproduction of bacteria and algae in papermaking, industrial circulating cooling water, metal processing lubricants, pulp, wood, paint and plywood. It can also be used as a slime control agent. , It is widely used in pulp and circulating cooling water system in paper mills. As a broad-spectrum and high-efficiency biocide, 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. At the same time, its branches can selectively bromide or oxidize the special enzyme metabolites of microorganisms, which will eventually lead to the death of microorganisms. This product has good peeling performance, no foam when used, liquid product and water can be dissolved in any ratio, low toxicity.
