Product Description

3,5-Dimethylpyrazole Description

3,5-Dimethylpyrazole is an organic heterocyclic compound with a five-membered pyrazole ring substituted with two methyl groups at positions 3 and 5. It is a colorless or pale yellow crystalline solid with a slight odor. The compound is widely used as a chemical intermediate in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Additionally, it is recognized for its role as a nitrification inhibitor in agriculture to improve nitrogen use efficiency in soils.

Key Features

1. Nitrification Inhibition:

   • Suppresses the activity of nitrifying bacteria in soil, reducing the conversion of ammonium to nitrate and slowing nitrogen loss from leaching or denitrification.

2. Versatility:

   • Serves as a versatile intermediate in the production of pharmaceuticals, agrochemicals, and other fine chemicals.

3. Solubility:

   • Exhibits good solubility in both water and organic solvents, allowing for a wide range of applications.

4. Thermal Stability:

   • Stable at room temperature with minimal risk of decomposition under normal conditions.

5. Environmentally Relevant:

   • Reduces nitrogen loss in agriculture, contributing to sustainable farming practices.

 

Applications

1. Agriculture

• Nitrification Inhibitor:
  • Used in fertilizers to improve nitrogen use efficiency by slowing down the conversion of ammonium to nitrate.
  • Reduces nitrogen losses through leaching and greenhouse gas emissions (e.g., nitrous oxide).
  • Commonly combined with urea-based fertilizers or ammonium-based fertilizers.

2. Pharmaceuticals

• Chemical Intermediate:
  • Used in the synthesis of active pharmaceutical ingredients (APIs) and heterocyclic compounds.

3. Agrochemicals

• Pesticides and Herbicides:
  • Serves as a building block in the formulation of crop protection chemicals.

4. Chemical Synthesis

• Catalysis:
  • Acts as a ligand in metal-catalyzed reactions.
• Intermediate:
  • Used for synthesizing dyes, polymers, and specialty chemicals.

5. Industrial Applications

• Corrosion Inhibitors:
  • Used in formulations to protect metals from corrosion in industrial processes.
