Application

TMAF commonly used as a weak base and fluoride ion source in various organic reactions, including nucleophilic substitution, functional group deprotection and ring opening polymerization. Unlike other fluoride sources, TMAF is compatible with many functional groups, making it a multifunctional reagent in synthetic chemistry.
Used as a fluorinating agent in medicinal chemistry for the preparation of radioactive tracers and protein modifications in biochemistry. The tetrahydrate form of TMAF is more stable and easier to handle than its anhydrous form.
Used as phase transfer catalysts in organic synthesis chemical reactions.
Used as cleaning agent in electrochemistry.
Used as selective fluorination catalysts and fluorinating agents, silane protecting group removal agents in chemical synthesis.
