2-Pyridinecarbonitrile,4-nitro-(9CI) - Introduction
Cyanonitropyridine is an organic compound with the chemical formula C6H3N3O2. The following is a description of its nature, use, preparation and safety information:
Nature:
Cyanonitropyridine is a yellow crystal, soluble in organic solvents such as ethanol and chloroform, and slightly soluble in water. It has strong oxidizing and explosive properties, and can explode or decompose by heating.
Use:
Cyanonitropyridine is mainly used in the preparation of drugs, dyes and explosives and other compounds. It can be used as an important intermediate in organic synthesis, can be used to synthesize other organic compounds or dyes, and can also be used as one of the components of chemiluminescence materials.
Method:
The preparation methods of Cyanonitropyridine are various, and one of the commonly used methods is obtained by nitration reaction. First, pyridine is reacted with concentrated nitric acid to obtain 2-nitropyridine. 2-Nitropyridine is then reacted with sodium cyanide or potassium cyanide to give Cyanonitropyridine.
Safety Information:
Because Cyanonitropyridine is explosive and highly oxidizing, it needs to be handled carefully. It should be kept away from fire, heat and combustibles, and stored in a cool, dry place. Wear protective gloves, goggles and protective clothing when in use. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help. If inhaled or ingested, seek medical attention immediately. During the operation, the correct laboratory operation specifications should be followed, and the operating conditions should be strictly controlled to reduce the risk.
