BSTFA-TMCS is an reagent used for the trimethylsilylation of alcohols, alkaloids, amines, biogenic, amines, carboxylic acids, phenols, and steriods. BSTFA-TMCS is also a derivatizing reagent for silylation,an derivatization procedure commonly used for sample analysis by gas chromatography. BSTFA-TMCS...
TMCS is a silylationcatalyst, rarely used alone in analytical applications but typically mixedwith other silylation reagents to increase their reactivity (e.g.,HMDS+TMCS+pyridine, BSTFA+TMCS, BSA+TMCS) in derivatization.Compounds derivatized with BSTFA+TMCS include opiates, PPC (PCPmetabolite) and ...
