General description

与 BSA 相比，BSTFA 是一种更强的硅烷化试剂。在大多数情况下，使用 BSTFA 代替 BSA，因为反应产物更易挥发，避免干扰色谱图中的早期峰。研究认为 BSTFA 和 TMCS 适用于定量反应。

Other Notes

三甲基硅烷基 (TMS) 试剂。

Application

在使用固相微萃取 (SPME) 与 GC-MS 联用测定塑料容器中痕量双酚 A 的过程中，将其用于水的衍生化。

Evidence is presented to confirm that N,O-bis(trimethylsilyl)acetamide does not form trimethylsilyl derivatives of sodium salts of many organic acids. Further evidence suggests that such derivatives are formed when either hydroxylamine hydrochloride or trimethylchlorosilane are also present. This presents a useful
