Silver(I) fluoride is the inorganic compound with the formula AgF. It is commonly found as the hygroscopic yellow anhydrous form, but various colorless hydrates, such as AgF·2H₂O and AgF·4H₂O, are also known. It is one of the three main fluorides of silver, the others being silver subfluoride and silver(II) fluoride. AgF has relatively few niche applications; it has been employed as a fluorination and desilylation reagent in organic synthesis and in aqueous solution as a topical caries treatment in dentistry.
