32111-21-0 - Introduction
2-Iodopyrazine is an organic compound with the chemical formula C4H3IN2. It is a derivative of pyrazine in which the No. 2 position is substituted by an iodine atom.
2-Iodopyrazine is a colorless crystalline solid that is stable at ambient temperature. It is soluble in organic solvents such as chloroform, methanol and ethanol, but insoluble in water. Its melting point is about 86-88°C.
The main use of 2-iodopyrazine is as an important intermediate in organic synthesis. It can be used to synthesize a variety of organic compounds, such as pharmaceuticals, pesticides and dyes. It can also be used as a complexing agent and catalyst.
A common method for preparing 2-iodopyrazine is through the reaction of pyrazine with compounds such as sodium iodide or cesium iodate. For example, pyrazine can be reacted with iodine and sodium chloride in ethanol, and then purified by extraction and crystallization to finally obtain 2-iodopyrazine.
When using 2-iodopyrazine, you need to pay attention to its safety information. It is an organic compound that has certain toxicity and may cause health hazards. Therefore, avoid direct contact with skin and eyes during the operation, and ensure that it is carried out under well-ventilated conditions. In addition, the compound should be stored and handled properly to avoid contact with oxidants and combustibles to prevent the risk of fire and explosion. When using or disposing of 2-iodopyrazine, relevant safety handling and precautions should be followed.
