| Product Name | 3,5-Dimethylpyrazole /3,5-DMP |
| CAS NO. | 67-51-6 |
| Molecular Formula | C5H8N2 |
| Structural Formula |   |
| Molecular Weight | 96.13 |
| Purity | ≥99.5% |
| Moisture | ≤0.5% |
| Melting Point | 106-108℃ |
| Application | 3,5-Dimethylpyrazole is used as a sealant for polyurethane and isocyanates. It serves as a nitrification inhibitor and nitrogen fertilizer efficiency enhancer in the fertilizer industry. This compound is a heterocyclic organic compound that can be used as a pharmaceutical intermediate. 3,5-Dimethylpyrazole mainly functions as a blocking agent to block isocyanate groups, forming stable chemical bonds with isocyanate groups at room temperature, and can undergo deblocking under heating conditions (typically 110-180℃) to release active isocyanate groups. Main advantages: The blocked product has good stability at room temperature, facilitating storage and transportation; moderate deblocking temperature with a wide processing window; 3,5-dimethylpyrazole can be recovered and recycled after deblocking. Typical applications: Production of one-component polyurethane coatings; preparation of blocked isocyanates for powder coatings; preparation of thermosetting polyurethane adhesives. |
