Derivatization reagents for GC, silylation, MSHFBA 85596.180 and accuratelyMSHFBA is used either alone or in combination with a catalyst (TMCS, TSIM) or another silylation reagent with or without solvent. The by product N methylheptafluorobutyric amide has a lower retention time than the silylating reagent. Especially useful for flame ionisation detection due to the large ratio of fluorine to silicon of 7: 1, since degradation of the excess of MSHFBA does not produce SiO but volatile, non corrosive silicon compounds.
