Overview

DBNPA (2,2-Dibromo-3-nitrilopropionamide) is a highly effective, non-oxidizing biocide that provides rapid microbial control in a wide range of industrial applications. DBNPA acts by quickly penetrating cell walls and inhibiting metabolic functions, resulting in near-instant cell death. It is non-persistent, hydrolyzing rapidly in water into non-toxic byproducts, which makes it especially attractive for systems requiring fast kill and rapid degradation. DBNPA is suitable for use in paper manufacturing, cooling water treatment, oil and gas fields, and reverse osmosis systems. It is particularly suitable for paper mills, cooling towers, oilfields, and membrane systems. With broad compatibility and a short half-life, DBNPA ensures effective microbial control without long-term residue. Its low odor and minimal impact on system chemistry make it a reliable choice for critical applications.
