Documented Uses

• Used as a catalyst, solvent for ESR, acid titrant, and with trifluoroacetic acid in peptide synthesis; [Merck Index]
• Silver trifluoromethanesulfonate is used in inorganic and organometallic chemistry to replace halide anions or ligands. (L833)
• PFAS -> Ultra Short Chain PFsulfonic acids
• Not Known or Reasonably Ascertainable
• Methanesulfonic acid, 1,1,1-trifluoro-: ACTIVE
• Silver and its compounds can be absorbed via inhalation, while silver compounds can also be absorbed orally and dermally. It distributes throughout the body in the blood, particularily to the liver. Insoluble silver salts are transformed into soluble silver sulfide albuminates, bind to amino or carboxyl groups in RNA, DNA, and proteins, or are reduced to metallic silver by ascorbic acid or catecholamines. Metallic silver is oxidized and may deposit in the tissues, causing arygria. Silver is eliminated primarily in
