|Section2= |Section3= }} Heptafluorobutyric acid (HFBA) is an organofluorine compound with the formula C3F7CO2H. As the fluorinated derivative of butyric acid, this colourless liquid is prepared by electrofluorination of the corresponding butyryl fluoride.〔Günter Siegemund, Werner Schwertfeger, Andrew Feiring, Bruce Smart, Fred Behr, Herward Vogel, Blaine McKusick "Fluorine Compounds, Organic" Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2002. 〕 ==Applications== HFBA has a variety of niche applications in analytical and synthetic chemistry. It is an ion pair reagent for reverse-phase HPLC. It is used in the sequencing, synthesis, and solubilizing of proteins and peptides. Esters derived from HFBA readily undergo condensation, owing to their electrophilicity. Specialized ligands for metal ions are generated capitalizing on this property, such as Eufod. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「heptafluorobutyric acid」の詳細全文を読む スポンサード リンク
