應用


  • Preanalytical factors influencing the results of ethanol analysis in postmortem specimens.: This study explores various preanalytical factors that affect the accuracy of ethanol analysis in postmortem specimens. Potassium fluoride is highlighted for its role in preventing the postmortem production of ethanol, thus ensuring reliable analytical results (Olds & Jones, 2024).

  • Enantioselective Synthesis of Chiral 2-Nitroallylic Amines via Cooperative Cation-Binding Catalysis.: This study reports the enantioselective synthesis of chiral 2-nitroallylic amines using a cooperative cation-binding catalysis approach involving potassium fluoride. It highlights the compound′s efficacy in asymmetric synthesis, an important area in organic chemistry (Park et al., 2023).

  • Synthesis of Sulfonyl Fluorides Using Direct Chloride/Fluoride Exchange in Potassium Fluoride and Water/Acetone.: The article presents a method for synthesizing sulfonyl fluorides using direct chloride/fluoride exchange in potassium fluoride and water/acetone, highlighting a practical and efficient approach to synthesizing these important compounds in organic chemistry (Bare, 2023).
