Description

Lamprecide CAS NO 654-66-0 is a specialized chemical compound, also known as 2,2-Dibromo-3-nitrilopropionamide (DBNPA), primarily recognized for its potent and rapid biocidal properties. This product is critical for industries requiring effective microbial control in aqueous systems, where it acts as a non-oxidizing biocide to prevent biofouling, spoilage, and microbiologically influenced corrosion. Key sectors that rely on this compound include water treatment, pulp and paper manufacturing, oilfield operations, and as a preservative in industrial formulations.

Application

• Industrial Water Treatment: Used as a slimicide and biocide in cooling towers, recirculating water systems, and process water to control bacteria, algae, and fungi.
• Pulp and Paper Industry: Acts as a preservative in paper mill white waters and starch slurries to prevent microbial degradation and spoilage.
• Oil and Gas Sector: Employed in oilfield water injection systems, fracturing fluids, and drilling muds to mitigate microbial contamination and biofilm formation.
• Metalworking Fluids: Serves as a preservative in synthetic and semi-synthetic metalworking fluids to extend fluid life and prevent odor.
• Paint and Coating Preservation: Used in water-based paints, adhesives, and polymer emulsions to provide in-can preservation against bacterial and fungal growth.
• Leather Processing: Applied in tanning processes and leather finishing baths as a biocide to prevent microbial damage.

Quality Control

Our Lamprecide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high performance. Each lot undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to meet the specifications required for industrial biocidal applications. Certificates of Analysis (COA) documenting purity, physical properties, and performance characteristics are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
