Skeletal formula of the nonaflate anion
Nonaflate, CF 3CF 2CF 2CF 2SO− 3, is the common name given to nonafluorobutanesulfonates, the salts or esters of perfluorobutanesulfonic acid. Its uses are similar to those of triflate.
It is a good leaving group.[1] It is a substitute for more toxic long-chain PFAS chemicals.[2]
