Selectfluor is a source of electrophilic fluorine. Selectfluor is very effective, safe, non-toxic, and easy to handle making it a convenient reagent for large scale synthesis. Historically electrophilic fluorinations were done using molecular fluorine (F2) which is very toxic and difficult to handle.




Common Uses:


Reagent for electrophilic fluorinations





Safety:


Selectfluor may be harmful to skin, eyes, or the respiratory tract. Selectfluor is a moderately strong oxidizing agent. Handle and store accordingly. Selectfluor should be stored at <30 C and can decompose exothermally above 100 C.
