2,2-Difluoroethyl trifluoromethanesulfonate

Description:
2,2-Difluoroethyl trifluoromethanesulfonate, with the CAS number 74427-22-8, is an organofluorine compound characterized by the presence of both difluoroethyl and trifluoromethanesulfonate functional groups. This compound is typically a colorless to pale yellow liquid at room temperature and is known for its high reactivity, particularly as an electrophilic reagent in organic synthesis. The trifluoromethanesulfonate group, also known as triflate, is a potent leaving group, making this compound valuable in nucleophilic substitution reactions. Its fluorinated structure contributes to its stability and unique properties, such as low polarity and high thermal stability. Additionally, 2,2-difluoroethyl trifluoromethanesulfonate is used in the synthesis of various fluorinated compounds and can serve as an intermediate in the production of pharmaceuticals and agrochemicals. However, due to its fluorinated nature, it may pose environmental and health concerns, necessitating careful handling and disposal in accordance with safety regulations.
