Application
The trimethylsilyl group is a frequently utilized monofunctional blocking group for protic organic and inorganic materials.
As the product eliminated during the silylation is neutral acetamide, SiSiB® PC9235 can be preferably used for substrates which are acid- or base-sensitive.
SiSiB® PC9235 can be used for blocking and protection of hydroxyl groups in natural products, e.g. amino acids, carbohydrates
SiSiB® PC9235 special silane can be used for blocking and protection of functional groups in organic intermediates.
The silylated derivatives show improved chemical stability than the original compounds and allow chemical reactions which otherwise would not be possible.
SiSiB® PC9235 can be used for formation of derivatives of H-acid compounds for analysis
The silylated derivatives are volatile and can therefore be determined by gas chromatography
Deblocking is preferably carried out by means of hydrolysis, giving high yields. In some cases, thermal elimination of the trimethylsilyl group is possible.
