Silver fluoride

Silver(I) fluoride AgF 99%: a soluble fluorinating reagent for organic synthesis, electronics, and catalysis. Buy from Ecotec — delivery across Russia.

Silver(I) fluoride (synonyms: AgF, silver monofluoride) is a colorless crystalline powder with a unique feature: complete solubility in water, which is not found in other silver halides. The substance is hygroscopic and, when moistened, quickly forms colorless solutions with pronounced corrosive properties. Ecotec products are manufactured according to internal specifications and are supplied with a purity of >= 99% for laboratory and industrial applications.

  • High reactivity: an effective source of F⁻ for selective fluorination in organic synthesis.
  • Purity 99%: controlled impurity levels (Cl⁻, Br⁻ <= 0.02%). COA with each batch.
  • Flexible pack sizes: 5 g to 250 g in sealed fluoroplastic jars; larger quantities on request.
  • Same-day dispatch: warehouse in Russia, fast delivery across Russia and CIS.
