| Description | 2,2-dibromo-3-nitrilopropionamide is a broad-spectrum non-food biocide. It is highly soluble in water and in some organic solvents such as acetone and ethanol. There is little information published on its environmental fate. It is moderately toxic to aquatic organisms. 2,2-dibromo-3-nitrilopropionamide has a moderate human oral toxicity, may be a reproduction/developmental toxin and is a recognised irritant. | | Chemical Properties | white powder | | Uses | A chemical additive to control bacterial contamination in ethanol fermentation. | | Production Methods | The commercial production of 2,2-dibromo-3-nitrilopropionamide (DBNPA) involves the bromination of cyanoacetamide in an aqueous medium. In this process, bromine is added to cyanoacetamide, resulting in the formation of DBNPA and hydrobromic acid. To improve bromine utilization and reduce costs, sodium hypochlorite is introduced as an oxidant to regenerate bromine from the hydrobromic acid, allowing further bromination. The reaction is conducted at 10–20 DegC to control exothermicity and prevent decomposition. | | General Description | Colorless to yellow liquid with a moldy pungent odor. | | Air & Water Reactions | Water soluble. | | Reactivity Profile | 2,2-Dibromo-2-cyanoacetamide is incompatible with bases, metals, oxidizing agents, acids. Dangerous gases may accumulate as a result of ignition and fire. | | Mechanism of action | Broad-spectrum antimicrobial activity | | Safety Profile | Poison by ingestion and
intravenous routes. A severe skin and eye
irritant. When heated to decomposition it
emits very toxic fumes of Brand NO,. See
