General description

Derivatization before a GC analysis helps in yielding distinctive products, which can be achieved using a derivatizing reagent that reacts with amino and hydroxyl functionalities quantitatively. 1-(Pentafluoropropionyl)imidazole (PFPI) is a derivatizing reagent which was found to give high yield of products than pentafluoropropionic anhydride during preparation of methyl ester/pentafluoropropionyl derivatives.

Application

PFPI may be used to incubate the lyophilized samples, for derivatization during GC/MS analysis to measure total d-chiro-Inositol content absorbed by rodents.

Other Notes

Derivatization agent for alcohols and carboxylic acids, etc. in GC
Reagent for methyl ester, pentafluoropropionyl.
