Introduction
5-Bromo-2-methyl-3-nitropyridine is an organic compound.
Properties: 5-Bromo-2-methyl-3-nitropyridine is a yellow to orange crystal with a special nitro taste. It is stable at room temperature, but decomposition may occur when heated or in contact with strong acids.
It can also be applied to chemical analysis, biomarkers, and organic synthesis.
Preparation method: The method of preparing 5-bromo-2-methyl-3-nitropyridine can be nitrification. A common method is to react 2-methylpyridine with concentrated nitric acid to produce 2-methyl-3-nitropyridine, and then use bromine to undergo bromination reaction in the presence of sulfuric acid to obtain the final product.
Safety information: 5-bromo-2-methyl-3-nitropyridine is relatively stable under general use conditions, but it is still necessary to pay attention to safe operation. It is a combustible substance and contact with open flames or high temperatures should be avoided. Appropriate personal protective equipment, such as laboratory gloves and safety glasses, should be worn during operation and avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water and seek medical attention promptly. Waste should be properly stored and disposed of to protect the environment.
