Introduction
2,5-Difluoroaniline.Quality:2,5-Difluoroaniline is a colorless to yellowish crystalline solid. It is stable at room temperature and slightly soluble in water, but easily soluble in organic solvents. It is a hydrophobic amine that has the characteristics of an aromatic amine and is prone to aromatic electron substitution reactions.Use:2,5-Difluoroaniline is often used as an important intermediate and starting substance in organic synthesis. It can also be used as a light-emitting layer material in organic light-emitting diodes (OLEDs).Method:In general, the preparation of 2,5-difluoroaniline can be achieved by introducing a fluorine atom at the position of aminobenzene. One synthesis method is to use chlorofluorodifluoromethane as a fluorine source, react with aminobenzene, and carry out nucleophilic aromatic substitution reaction under alkaline conditions to generate 2,5-difluoroaniline.Safety Information:2,5-Difluoroaniline is a toxic compound that is irritating and corrosive. When using or storing, care should be taken to avoid contact with the skin, eyes and respiratory tract. Appropriate personal protective equipment such as gloves, goggles, and protective clothing should be worn during operation. Avoid contact with strong oxidizing agents and acids to prevent dangerous reactions. When disposing of waste, relevant laws and regulations should be complied with and appropriate disposal measures should be taken.
