Premium Dibromocyanoacetamide(DBNPA) CAS 10222-01-2
Dibromocyanoacetamide, universally known as DBNPA, is a premium-grade, broad-spectrum, and non-oxidizing chemical biocide. DBNPA exhibits an extremely rapid kill rate against a diverse range of microorganisms, including bacteria, fungi, algae, and industrial slimes.
As a certified global DBNPA manufacturer and supplier, our factory delivers high-purity industrial biocides that provide an ideal combination of high efficacy and eco-friendly performance. The most prominent advantage of DBNPA is its quick-acting sterilization followed by rapid hydrolysis into completely non-toxic sub-products under both acidic and alkaline conditions. This unique property ensures comprehensive microbial control without leaving persistent hazardous chemical residues in downstream environments.
- Ultra-Fast Microbial Elimination: Rapidly penetrates the cell membranes of microorganisms, disrupting vital protein groups and achieving complete microbial death within minutes.
- Eco-Friendly & Zero Residue: Hydrolyzes swiftly after fulfilling its biocidal action, leaving no residual toxicity, no foam build-up, and zero long-term environmental accumulation.
- Broad-Spectrum Biofilm Stripping: Highly effective against both planktonic and sessile bacteria, effectively stripping away stubborn slime clumps to restore industrial equipment efficiency.
- Excellent Synergistic Compatibility: Functions perfectly alongside other chlorine-containing or non-oxidizing biocides, delivering a powerful synergistic effect while lowering equipment corrosion rates.

2,2-Dibromo-2-cyanoacetamide Applications
Thanks to its highly reactive chemical structure, DBNPA is utilized as a core pharmaceutical intermediate, industrial water treatment agent, and slime control additive across various global manufacturing sectors:
- Industrial Circulating Water Systems: DBNPA is widely deployed in open or closed cooling towers, air conditioning water systems, and heat exchangers. Maintaining a dosage concentration of approximately 15-20ppm of DBNPA effectively controls bacteria and algae, while stripping away original slime clumps to maximize cooling tower evaporation efficiency.
- Pulp and Paper Manufacturing: In paper mill systems, microbial slime formation causes frequent paper breaks and reduces final product quality. Our DBNPA serves as an excellent, non-staining slime control agent for paper mill pulp, preventing bio-slime generation throughout circulating water networks.
- Oilfield Reinjection Water & Drilling Mud: Used extensively in oil and gas extraction to protect downhole operations from microbial corrosion. It prevents sulfate-reducing bacteria (SRB) from destroying metallic pipelines, maintaining oilfield system integrity.
- Metalworking Fluids & Lubricants: Incorporated directly into metalworking cooling liquids, oil emulsions, and synthetic lubricants to inhibit bacterial growth in high-temperature fibers, prolonging fluid service life.
- Wood, Paint, and Plywood Preservation: Acts as a powerful dry-film and wet-state preservative in heavy industrial paints, structural plywood adhesives, and raw wood processing to eliminate mold and fiber-destroying fungi.
Dibromocyanoacetamide (DBNPA) Product FAQ
Q1: What are the alternative chemical terms and trade names for DBNPA?
DBNPA is chemically referred to as 2,2-Dibromo-2-cyanoacetamide or 2,2-Dibromo-3-nitrilopropionamide. Commercially, water treatment engineers often refer to it via prominent international trade names such as AQUCAR DB 20, AQUCAR DB 5, AQUCAR DB 100, X-CIDE 600, and XF-993D equivalent formulas.
Q2: Why does DBNPA perform better than oxidizing biocides like chlorine?
Unlike chlorine or ozone, DBNPA is a non-oxidizing biocide that eliminates microorganisms through direct cellular chemical interaction rather than oxidation. It remains highly effective in systems with high organic loads, does not produce carcinogenic trihalomethanes (THMs), and works perfectly across broad pH ranges.
Q3: How fast does DBNPA degrade once introduced into water treatment networks?
The hydrolysis rate of DBNPA depends heavily on pH and temperature. It rapidly breaks down into harmless carbon dioxide, ammonia, and bromide ions, making it ideal for once-through cooling systems and eco-regulated discharge waters.
