Chlorodimethyl(pentafluorophenyl)silane, 96%

Description

CAS: 20082-71-7 | C8H6ClF5Si | 260.66 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
