Introduction
2-Amino-5-nitropyridine is an organic compound. It has yellow crystals or powders and is soluble in organic solvents and acidic solutions.
2-Amino-5-nitropyridine is mainly used in the preparation of mine mercury and blasting agents. The amino and nitro groups it contains make it highly explosive, and it is used as an intermediate in the preparation of explosives in the military and explosives industry.
It is prepared in a variety of ways, and a common preparation method is synthesized by nitrosylation reaction, that is, 2-aminopyridine and nitric acid react to form 2-amino-5-nitropyridine. It is necessary to control the reaction conditions and pay attention to safe operation during preparation, because 2-amino-5-nitropyridine is an explosive substance and is dangerous. When preparing, it is necessary to follow the relevant safety operation procedures and carry out protective measures.
During storage and operation, it should be kept dry, avoid contact with oxidants, acids and combustibles, and stored in fireproof and explosion-proof containers. During handling and transportation, it is necessary to comply with relevant regulations to ensure safe use.
