Common Name: DBNPA Biocide
Chemical Name: 2,2-Dibromo-3-nitrilo-propionamide
CAS No. 10222-01-2 EINECS No. 233-539-7
UN Number: 1759 RIDADR : UN 1759 8/PG 3
Molecular weight: 241.84 Molecular Formula: C3H2ON2Br2
White crystals. Melting point of 125℃, it can soluble in common organic solvents (such as acetone, benzene, dimethylformamide, ethanol, polyethylene glycol, etc.), slightly soluble in water (25 ℃, 100g water dissolved 1.5g). Its aqueous solution is more stable under acidic conditions, and easy hydrolysis in alkaline conditions. Increasing the pH value, heating with ultraviolet light or fluorescent light, can make its dissolution rate greatly accelerated. Easy to be reductant, such as hydrogen bromide and bromine into non-toxic cyanide acetamide, the sterilization rate greatly reduced. When its pH value increase from 6.7 to 9.7, the half-life will change from 37.0h into 0.11h.
Melting Point ℃
It is used as anti-microbial agent, controlling bacterial, fungal and algal growth in industrial water systems like cooling towers, pulp and paper mill process water, oil-recovery systems and air-conditioning systems.
It is a chemical additive to control bacterial contamination in ethanol fermentation.
