High impact information on Pentafluoropropionic anhydride

• DNA from liver tissue was also analyzed by alkaline hydrolysis of 4-ABP, derivatization with pentafluoropropionic anhydride, and gas chromatography/mass spectroscopy analysis [1].
• Four anabolic steroid metabolites to be derivatized by Pentafluoropropionic anhydride (PFPA) were determined using gas chromatography/mass spectrometry (GC/MS) with negative chemical ionization (NCI) and NCI/MS/MS [2].

• Acid extraction, partial purification on Amberlite CG 120, and derivatization with pentafluoropropionic anhydride preceded the gas chromatography-mass spectrometry [4].
• Four monoalkylhydrazines were analyzed in whole blood by reaction with pentafluorobenzaldehyde to form stable hydrazone derivatives which were extracted and subsequently reacted with pentafluoropropionic anhydride to give products which were very sensitive to electron-capture detection when analyzed by gas chromatography [5].

Biological context of Pentafluoropropionic anhydride

• The assay procedure involves esterification of both hydroxyl groups of sobrerol with pentafluoropropionic anhydride to form the diester which can be quantitated using gas-liquid chromatography-electron-capture detection [6].
• The method employs differential pH extraction of 1 mL samples, extractive acylation with pentafluoropropionic anhydride (PFPA), GC separation on a fused-silica capillary column (DB-1701), and detection by electron capture detector (ECD) or mass spectroscopy (MS) [7].
• The procedure involves extraction with a liquid ion exchanger followed by acetylation and reaction with pentafluoropropionic anhydride [8].

Associations of Pentafluoropropionic anhydride with other chemical compounds

• The corresponding amines (to the isocyanates), 2,4- and 2,6-toluenediamine (2,4- and 2,6-TDA), were determined in each fraction after sulfuric acid hydrolysis as pentafluoropropionic anhydride derivatives by capillary gas chromatography and chemical ionisation mass spectrometry monitoring negative ions [9].
• This method involves enzyme hydrolysis in the presence of a deuterated internal standard, liquid-liquid extraction, and derivatization with pentafluoropropionic anhydride and pentafluoropropanol [10].
