Silylation Derivatization Reagents
• Replace active hydrogen, reducing polarity and making the
compounds more volatile.
• Increase stability of derivatives.
Silylation is the most widely used derivatization procedure for
sample analysis by GC. In silylation, an active hydrogen is re-
placed by an alkylsilyl group such as trimethylsilyl (TMS) or
tert-butyldimethylsilyl (tert-BDMS). Silyl derivatives are more
volatile, less polar, and more thermally stable. As a result, GC
separation is improved and detection is enhanced.
Both TMS and tert-BDMS reagents are suitable for a wide vari-
ety of compounds and can be used for many GC applications.
(Note that silylation reagents are generally moisture-sensitive
and must be sealed to prevent deactivation.)
