2-Chloro-6-(trichloromethyl)pyridine is a nitrification inhibitor used to limit NO and N2O emissions from crops. Improves nitrogen use efficiency. Environmental toxin on US EPA Toxic Release Inventory list (TRI) list.
Colorless to white crystalline solid with a mild, sweet odor
2-Chloro-6-(trichloromethyl)pyridine is
Bactericide used to inhibit Nitrosomonas spp. from oxidizing ammonium ions in soil.
Fertilizer additive to control nitrification and prevent loss of soil nitrogen.
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.
Colorless crystals or off-white crystalline solid.
Nitrapyrin is a base. Reacts exothermically with acids.
Liver damage. Questionable carcinogen.
Flash point data for Nitrapyrin are not available. Nitrapyrin is probably combustible.
Flammability and Explosibility
Non flammable
Nitrapyrin, also called N serve, is a nitrification
inhibitor
Poison by ingestion.
Moderately toxic by skin contact.
Experimental reproductive effects. Mutation
data reported. When heated to
decomposition it emits very toxic fumes of
Cland NOx.
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).
