| Boiling Point | 258.2±35.0°C at 760 mmHg |
| Density | 1.582 g/cm³ or 1.6±0.1 g/cm³ |
| Flash Point | 134.9±11.5°C |
| Solubility | Insoluble in water, soluble in organic solvents such as methanol, ethanol, and acetone |
| Usage | Used as a nitrification inhibitor in agriculture to increase nitrogen use efficiency and reduce nitrogen losses through leaching and denitrification. It also has applications in soil nutrient protection and environmental management. |
| Mechanism of Action | By inhibiting the activity of ammonium-oxidizing bacteria, Nitrapyrin prolongs the existence of ammonium nitrogen in soil and reduces the conversion of ammonium nitrogen to nitrate nitrogen, thereby enhancing nitrogen utilization and reducing nitrogen losses. |
| Storage Conditions | Store in a cool, dry place, away from heat, sparks, and open flames. Keep container tightly closed and store at 0-6°C. |
| Safety Hazards | May cause irritation to eyes, skin, and respiratory tract. Ingestion may be harmful. Wear appropriate protective equipment and handle with care. Avoid contact with oxidizing agents and incompatible chemicals. |
