Tetra-n-butylammonium fluoride, commonly abbreviated to TBAF and n-Bu₄NF, is a quaternary ammonium salt with the chemical formula (CH₃CH₂CH₂CH₂)₄N⁺F⁻. It is commercially available as the white solid trihydrate and as a solution in tetrahydrofuran. TBAF is used as a source of fluoride ion in organic solvents.
