General description

Chlorodimethyl(pentafluorophenyl)silane is a silylated derivative employed for derivatization prior to gas chromatographic analysis of the analyte. It is basically used:
  • To increase analyte volatility.
  • To increase response.
  • To suppress the activity of an active functional group.

Other Notes

Extremely sensitive derivatizing agent for the analysis of sterols and lower aliphatic alcohols by electron capture gas chromatography
