1-硝基-1H-吡唑 - Introduction
1-nitropyrazole is an organic compound with the chemical formula C3H2N3O2. It is a white crystalline solid with high thermal stability and explosive properties. It is a high-energy compound that can be used to prepare explosives and propellants.
The preparation method of 1-nitropyrazole can be prepared by the reaction of ferrous sulfate and silver nitrate. First, ferrous sulfate and silver nitrate solution were mixed, stirred at low temperature, and the precipitated 1-nitropyrazole was extracted and purified by cold pressing.
Because 1-nitropyrazole has explosive properties, it is necessary to pay attention to safety when preparing and handling. It is a sensitive explosive substance that can cause an explosion by friction, impact or electrostatic sparks. It is necessary to wear protective clothing, goggles and other protective equipment during operation, and operate in a well-ventilated laboratory. In addition, it is also a toxic substance, contact or inhalation can cause harm to human health, so avoid contact with skin, eyes and respiratory tract.
1-nitropyrazole as a high-energy compound is widely used in military, blasting equipment industry, propellant, filling herbs and geological exploration and other fields. However, due to its explosive and toxic nature, it must be used with care and in accordance with relevant regulations and safety guidelines.
