1049026-49-4 - Introduction
2-Bromo-5-methylsulfanylpyrazine is an organic compound with the chemical formula C6H4BrN3S. The following is a description of its nature, use, preparation and safety information:
Nature:
2-Bromo-5-methylthiopyrazine is a white or pale yellow crystalline solid with a strong sulfide odor. It is stable at room temperature and has low solubility in water, but has good solubility in organic solvents. It belongs to the pyrazine class of compounds and has structural features similar to pyrazine.
Use:
2-Bromo-5-methylsulfanylpyrazine is a common organic synthesis intermediate, which has a wide range of applications in the fields of pesticides, drugs and dyes. It is mainly used to synthesize drugs and chemicals such as antibiotics, fungicides and disinfectants. In addition, it can also be used as a chemical analysis reagent and a raw material for laboratory research.
Preparation Method:
The preparation of 2-bromo-5-methylthio-pyrazine is usually accomplished by iodination and amination reactions. The specific steps can be divided into the following steps: first, bromine is reacted with pyrazine to generate bromopyrazine; then, bromopyrazine is reacted with sulfamide to generate bromopyrazine compound substituted with sulfamide; finally, bromopyrazine compound is reacted with methylthioamine to generate 2-bromo-5-methylthiopyrazine.
Safety Information:
2-Bromo-5-methylthiopyrazine has no obvious acute toxicity to human body at room temperature, but has irritating effect on skin, eyes and respiratory tract. Therefore, contact with skin and eyes should be avoided during use, and protective gloves, goggles and protective masks should be provided if necessary. In addition, it should also be kept away from ignition and oxidizing agents and stored properly.
