氯二甲基（五氟苯基）硅烷是一种极其灵敏的衍生剂，用于通过电子捕获气相色谱法分析固醇和低级脂肪醇（1），（2），（3）。 Chlorodimethyl(pentafluorophenyl)silane is an extremely sensitive derivatizing agent for the analysis of sterols and lower aliphatic alcohols by electron capture gas chromatography(1),(2),(3). Application It is used as a GC reagent for detection of sterols at low concentration as flophemesyl derivatives, readily detected by electron capture.
