SILYLATION REAGENTS BSA N,O-Bis(trimethylsilyl)acetamide • Forms highly stable TMS derivatives with most organic functional groups under mild reaction conditions. BSTFA-Regisil ® BSTFA +TMCS (1%, 10%) N,O-Bis(trimethylsilyl)trifluoroacetamide • Reacts faster and more completely than BSA, due to presence of trifluoroacetyl group. • The high volatility of BSTFA and its byproducts results in separation of early eluting peaks. • Highly volatile and stable products result in low detector noise and fouling. • Excellent solubility. • Addition of TMCS catalyzes reactions of hindered functional groups in secondary alcohols and amines. HMDS Hexamethyldisilazane • Weak TMS donor, used for silylation of carbohydrates. • Used as mixture with pyridine and trifluoroacetic acid. MSTFA N-Methyltrimethylsilyltrifluoroacetamide • Most volatile of the TMS-acetamides. • Useful in the analysis of volatile trace materials.
