Nature:
4,5, 6,7-tetrahydropyrazolo [1,5-A] pyrimidine is a white crystal with the property of being soluble in organic solvents. It has a melting point of 180-183°C and a boiling point of 379.8°C. This compound is relatively stable, but will be affected by light and fade.
Use:
4,5, 6,7-tetrahydropyrazolo [1,5-A] pyrimidine is mainly used to synthesize other organic compounds, especially compounds with biological activity. It is commonly used in drug development and pesticide synthesis.
Method:
The preparation method of 4,5, 6,7-tetrahydropyrazolo [1,5-A] pyrimidine is complicated. One common method is synthesis by a multi-step reaction. First, 5-bromopyrimidine reacts with glutathione to form 5-(δ-glutamino-ornithine)-4-bromopyrimidine. Then, through condensation reaction, oxidation reaction and elimination reaction, 4,5, 6,7-tetrahydropyrazolo [1,5-A] pyrimidine is finally obtained.
Safety Information:
4,5, 6,7-tetrahydropyrazolo [1,5-A] pyrimidine is generally relatively safe under normal conditions of use. However, because it is a chemical substance, it should be used in accordance with the relevant laboratory practices. Direct contact with skin or eyes may cause irritation, so appropriate use of personal protective equipment is required. If ingested or inhaled in excess, seek medical attention immediately. When storing and handling the compound, care should be taken to avoid ignition and other flammable hazards, store in sealed containers, and prevent mixing with oxidants and acids.
