MSTFA可用于甲硅烷基化过程，以使用GC-MS对类固醇激素17α-乙炔雌二醇（EE2）和雌酮进行测定。MSTFA与三甲基甲硅烷基氯（TMCS）一起在乙酸乙酯、乙腈和二氯甲烷溶剂中可导致三甲基甲硅烷基（TMS）和叔丁基二甲基甲硅烷基（TBS）衍生物的形成。
适用于胺，氨基酸，羧基，羟胺，吲哚烷基胺，正亚硝基氨基酸，核苷，酚烷基胺，5-羟色胺和色胺的衍生化。

Glucosinolates are defense-related secondary metabolites found in Brassicaceae. When Brassicaceae come under attack, glucosinolates are hydrolyzed into different forms of glucosinolate hydrolysis products (GHPs). Among the GHPs, isothiocyanates are the most comprehensively characterized defensive compounds, whereas the functional study of
