N-Fluoropyridinium triflate is an organofluorine compound with the formula [C<sub>5</sub>H<sub>5</sub>NF]O<sub>3</sub>SCF<sub>3</sub>. It is a white solid with low solubility in polar organic solvents. The compound is used as an electrophilic fluorinating agent. It is a salt, consisting of the N-fluoropyridinium cation ([C<sub>5</sub>H<sub>5</sub>NF]<sup>+</sup>) and the triflate anion. Related reagents include Selectfluor, which is also an N-fluorinated salt.
N-Fluoropyridinium cations are not only electrophilic fluorinating agents (i.e., sources of "F<sup>+</sup>"), they are also one-electron oxidants.
