Applications
Pentafluorobenzenesulfonyl chloride is used as derivatizing reagent for simultaneous determination of fluoxetine and p-trifluoromethylphenol, an O-dealkylated metabolite of fluoxetine in human liver microsomes. It is also used for electrophore labeling of small tyrosyl peptides for their analysis by gas chromatography with electron-capture detection. It is also employed as derivatizing reagent for amphetamine in determination of amphetamine in human plasma samples using gas chromatography with electron-capture detection.

Solubility
Soluble in water (reacts slowly).

Notes
Moisture Sensitive. Store away from oxidizing agents, active metals and bases, water/moisture. Keep the container tightly closed in a cool, dry place. Store under inert gas.
