Silylation with MSTFA
Summary
Type: GCApplication #: 213111
Catalog#: 701270.201 - MSTFA. 20x1 ml
Detection: GC, especially GC-FID
Conditions: Very strong TMS donor which does not cause any noticeable FID fouling even after long-time measuring series.
The already good solution characteristics can be improved by addition of submolar quantities of protic solvents (e.g. TFA for extremely polar compounds such as hydrochlorides) or pyridine (e.g. for carbohydrates).
Recommended application: carboxylic acids, hydroxy and ketocarboxylic acids, amino acids, amines, alcohols, polyalcohols, sugars, mercaptans and similar compounds with active hydrogen atoms. Even amine hydrochlorides can be silylated directly.
