General description
1-（三甲基硅烷）咪唑-吡啶混合物用于湿态糖样品和类固醇中受阻羟基的衍生化，并且可以和氟化酰化试剂一起进行氨基酸的衍生化。对于中度受阻或反应缓慢的化合物，吡啶是一种特别有用的1-（三甲基硅烷）咪唑（TMSI）溶剂，因为在涉及有机氯硅烷的硅烷化反应中它可以作为HCl受体。

Two new procedures for the gas-chromatographic analysis of monosaccharides are reported. One involves derivatization of the sugars by reaction with O-benzylhydroxylamine followed by trifluoroacetylation with N-methylbis(trifluoroacetamide) and chromatography on a DB-1701 capillary column. This technique probably provides the best resolution
