WebSilylation is an ideal procedure for the GC analysis of non-volatile and thermolabile compounds. Compared to their parent compounds, trimethylsilyl (TMS) derivatives are more volatile, less polar and more thermotolerant. In silylation, an active hydrogen in –OH, –COOH, =NH, –NH2 or –SH is replaced by a trimethylsilyl group. A trimethylsilyl group (abbreviated TMS) is a functional group in organic chemistry. This group consists of three methyl groups bonded to a silicon atom [−Si(CH3)3], which is in turn bonded to the rest of a molecule. This structural group is characterized by chemical inertness and a large molecular … See more Related to trimethylsilyl groups are "super" silyl groups of which there exist two varieties: A silicon group connected to three trimethylsilyl groups makes a tri(trimethylsilyl)silyl group (TTMSS or TMS3Si) and a … See more • Trimethylsilanol • Trimethylsilylacetylene • Trimethylsilyl chloride See more • Identification of Silylation Artifacts in Derivatization Reactions for Gas Chromatography See more In organic synthesis, TMS group is used as a protecting group for alcohols.
