DBNPA
chemical compound

DBNPA (2,2-dibromo-3-nitrilopropionamide) is a brominated acetamide. Its synonyms include 2,2-dibromo-2-carbamoylacetonitrile, α,α-dibromo-α-cyanoacetamide, and dibromocyanoacetamide. The physical appearance of DBNPA is an off-white solid at ambient temperatures with a mild antiseptic odor and is often sold in powder form. DBNPA is often used as an algicide, bactericide and fungicide in industrial water treatment systems and as a preservative used in the manufacture of paper, glues, coatings, enhanced oil recovery systems and metalworking.
History
The first documented synthesis of DBNPA was carried out by Bernhard Conrad Hesse in 1896. DBNPA's practical applications were not explored until 1947, when it started being used as a seed and plant fungicide. Despite this early use, its complete potential as an antibacterial agent was not yet understood.
By the early 1970s, DBNPA had gained attention for its effectiveness in controlling microbial contaminations in industrial settings. It started being widely used as a slimicide in papermaking systems, cooling water treatment, and other industries vulnerable to biofouling. DBNPA's demonstrated biocidal efficacy led to its official registration as a pesticide in the US in 1972.
“DBNPA” enters the record as chemical compound. Crown Archives preserves that source wording while asking what DBNPA, chemical and compound can confirm, complicate or overturn.
Why this record matters
“DBNPA” is worth following because a concise public description often conceals a longer documentary argument. Here, DBNPA, chemical and compound provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q5204411. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1896, 1947 and 1972.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
