Nitrapyrin Chemical Properties,Usage,Production

Uses

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.

Chemical Properties

Crystals.

Physical properties

Colorless to white crystalline solid with a mild, sweet odor

Uses

2-Chloro-6-(trichloromethyl)pyridine is

Uses

Fertilizer additive to control nitrification and prevent loss of soil nitrogen.

Uses

Bactericide used to inhibit Nitrosomonas spp. from oxidizing ammonium ions in soil.

Definition

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.

General Description

Colorless crystals or off-white crystalline solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Nitrapyrin is a base. Reacts exothermically with acids.

Hazard

Liver damage. Questionable carcinogen.

Fire Hazard

Flash point data for Nitrapyrin are not available. Nitrapyrin is probably combustible.

Flammability and Explosibility

Non flammable

Agricultural Uses

Nitrapyrin, also called N serve, is a nitrification inhibitor

Safety Profile

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.

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).
