2,2-Dibromo-2-Cyanoacetamide CAS 10222-01-2

2,2-Dibromo-2-cyanoacetamide is one of the most widely used non-oxidizing biocides in industrial circulating water systems. It can rapidly penetrate microbial cell walls, damage enzyme systems and nucleic acid structures, and efficiently kill common waterborne microorganisms such as bacteria, fungi and algae.

Meanwhile, it effectively removes biofilm from the surfaces of pipelines and heat exchangers, improving heat transfer efficiency and reducing equipment corrosion risks.Its outstanding advantages include fast degradation in water, low residue, environmental friendliness and no long-term cumulative pollution. It also has good compatibility with commonly used scale inhibitors and corrosion inhibitors. Widely applied in circulating cooling water systems in petrochemical, power, steel, chemical and other industries, it is a key agent ensuring continuous production.

In papermaking, pulp and white water systems are highly susceptible to microbial growth, leading to slime, deposits, web breaks, pinholes in paper and equipment clogging. DBNPA can rapidly inhibit microbial proliferation and control slime formation without generating foam, and does not affect paper strength or brightness.

It decomposes quickly in alkaline white water systems without interfering with subsequent papermaking and sizing processes. It also reduces odor and spoilage, extends the recycling cycle of white water, and enhances the operational stability of paper machines, making it an important preservative in modern papermaking processes.

Water-based cutting fluids, emulsions, rolling fluids and other metalworking fluids are prone to microbial contamination during use, resulting in odor, stratification and failure. As a highly effective preservative, DBNPA inhibits the growth of bacteria and fungi at low concentrations, extending the service life of working fluids and reducing replacement frequency.It acts fast without damaging lubricating or anti-rust components, causes no corrosion to metal workpieces, and is compatible with various water-soluble processing fluid systems. It is widely used in machinery manufacturing, automotive parts processing and other fields.

Oilfield reinjection water and fracturing fluids often contain harmful microorganisms such as sulfate-reducing bacteria and iron bacteria, which can easily cause pipeline corrosion, hydrogen sulfide generation and formation plugging. DBNPA can efficiently kill such bacteria, control biofouling and corrosion hazards, and ensure unobstructed water injection systems.Meanwhile, its degradation products are formation-friendly and do not cause secondary pollution. Suitable for water treatment processes in offshore and onshore oilfields, it plays an important role in improving oil recovery efficiency and reducing maintenance costs.

In water-based coatings, latexes, adhesives, printing inks and other products, DBNPA can be used as a preservative and antifungal agent to prevent mold, deterioration and odor during storage and use, maintaining stable product performance.Due to its broad-spectrum bactericidal activity, rapid action, low toxicity and easy degradability, it is also used in small amounts in some detergent and cleaning product formulations to enhance microbial resistance and shelf life.

In the field of fine chemicals, DBNPA can also serve as an organic synthesis intermediate, participating in bromination, amidation and other reactions for the preparation of active compounds such as pharmaceuticals and pesticides.The bromine atom and cyano group in its molecular structure exhibit high reactivity, allowing it to act as a versatile synthetic building block in the construction of drug molecules and heterocyclic compounds.
