Molecular formula: C₃H₂Br₂N₂O

Molecular weight:242
CAS NO.: 10222-01-2

Chemical Name: 2,2 Dibromo 3 Nitrilopropionamide, DBNPA

Application:

It is a kind of Water Treatment Material . Biocides in broad spectrum. It is widely used in industrial circulating water system, large air-condition and the large center of sewage treatment to eliminate microorganism and alga and shuck off clay. It is also used in the process of paper making to prevent reducing quality of paper by generation of microorganism. It is suitable for metal cutting of cooling liquor, recovery system of oil, latex and ply-woods as anti-spy biocides. It has following advantages: Easy to handle. No unusual oxidation hazards. Similar performance and safety in paper and oilfield applications. Used for slime control in the wet-end of the paper mill and performs exceptionally well against slime-forming bacteria.
