2,2-Dibromo-3-nitrilopropionamide

2,2-Dibromo-3-nitrilopropionamide, commonly abbreviated as DBNPA, is a fast-acting halogenated biocide available under trade names including DBNPA 7287, X-CIDE 508, Biomate 723, Amerstat 300, and BIOBROM C-103. It carries CAS number 10222-01-2 and EC number 233-539-7. No E-code designation applies to this substance.

DBNPA is used as a non-oxidising biocide in industrial water treatment systems, where it controls bacterial and algal growth in cooling towers and process water circuits by reacting with and disrupting microbial cell function. In pulp and paper manufacturing, it prevents slime-forming microorganism colonies that compromise paper machine efficiency. It also serves as a preservative in metalworking fluids and oil field injection water.

DBNPA is supplied as a technical-grade white powder and is subject to REACH registration requirements within the EU. It is classified under HS code 29209090. Packaging formats typically include fibre drums and sealed bags; buyers should confirm available pack sizes and SDS documentation at point of enquiry.
