Applications

It is used as a GC reagent for detection of sterols at low concentration as flophemesyl derivatives, readily detected by electron capture. Chlorodimethyl(pentafluorophenyl)silane is an extremely sensitive derivatizing agent for the analysis of sterols and lower aliphatic alcohols by electron capture gas chromatography.

Notes

Moisture sensitive. Store away from strong bases, water/moisture and oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Store under inert gas.
