ChEBI: Nitrapyrin is a chloropyridine that is 2-chloropyridine which is substituted by a trichloromethyl group at position 6. It is a nitrification inhibitor that is co-applied with nitrogen fertilizer in agroecosystems. It has a role as a nitrification inhibitor, an antibacterial agent and an agrochemical. | [Flammability and Explosibility]
Nonflammable | [Agricultural Uses]
Nitrapyrin, also called N serve, is a nitrification
inhibitor | [Environmental Fate]
Biological. 6-Chloropicolinic acid and carbon dioxide were reported as biodegradation
products (Verschueren, 1983).
Soil. Hydrolyzes in soil to 6-chloropyridine-2-carboxylic acid (Worthing and Hance,
1991).
Photolytic. Photolysis of nitrapyrin in water yielded 6-chloropicolinic acid, 6-hydroxypicolinic
acid and an unidentified polar material (Verschueren, 1983).
Chemical/Physical. Emits toxic fumes of nitrogen oxides and chlorides when heated
to decomposition (Sax and Lewis, 1987; Lewis, 1990). |
