2,2-Dibromo-3-nitrilo-propionamide (DBNPA) is a broad-spectrum biocide primarily used as a microbial preservative and fungicide. It is highly effective in controlling bacteria, fungi, and algae in industrial water systems, cooling towers, and other water treatment applications. DBNPA is also used in oilfield applications, textiles, and cosmetic formulations as an antimicrobial agent.
