Abstract
Abstract Trifluoropropyl, heptafluoropentyl, and pentafluorophenyl groups substituted into silyl ethers of sterols provide stable and volatile derivatives useful in the gas chromatography of sterols. The first two show low sensitivity toward electron capture detection (ECD), but the pentafluorophenyl group is more sensitive to ECD than the currently used chloromethyl group and is more thermally stable than the heptafluorobutyryl group.
