General description
N,O-双(三甲基硅烷基)三氟乙酰胺(BSTFA)是一种优良的硅基化试剂。对于一些空间位阻的一级或二级硝基化合物，N,O-双(三甲基硅基)乙酰胺和BSTFA比常规硅基化条件结果更佳。BSTFA已在胺衍生化中得到应用。其适于羧酸、酚类、脲类、酰胺类、醇类的水化反应。
Application
更多信息请参见产品信息
BSTFA + 1% TMCS（三甲基硅基）溶于乙酸乙酯、乙腈和二氯甲烷溶剂中的情况下，可用于通过气相色谱-质谱联用技术(GC-MS)进行的甾体激素17a-乙炔雌醇(EE2)硅基化反应。此外，其还可用于内源性2-单甘油酯（存在于与大麻素受体结合的犬肠道中）的硅基化。
