Dimethyl Pyrazole Phosphate (CAS 202809-73-4) is an agricultural-grade nitrification inhibitor supplied as a high-purity crystalline solid or a liquid formulation, used in fertilizer coatings and fertigation to limit nitrogen leaching and nitrous oxide emissions. It is known for its low volatility and high effectiveness at significantly lower dosage rates than traditional inhibitors.
This Specialty Chemical works by temporarily inhibiting the activity of Nitrosomonas bacteria in the soil. By keeping nitrogen in the ammonium form longer, it reduces leaching and nitrous oxide emissions effectively.
The product is available in high-purity crystalline form or as a liquid formulation for coating fertilizers. It exhibits excellent compatibility with a wide range of granular and fluid nitrogen-based fertilizers.

Applications
- Fertilizer Coating: Applied to Urea or NPK fertilizers to extend the availability of nitrogen to crops over several weeks.
- Greenhouse Agriculture: Used in fertigation systems to prevent nitrate accumulation in sensitive leafy vegetable crops.
- Environmental Protection: Reduces groundwater nitrate contamination and greenhouse gas emissions in industrial farming operations.
