Ɑ-Methoxy-ω-Trimethoxysilylpropylurea PEG

The trimethoxysilyl functionality allows the pegylation of a variety of surfaces (e.g. glass, metals) and introduces PEG on hydroxylated surfaces in a one step procedure. Compared to Triethoxysilyl- the Trimethoxysilyl-PEG is more reactive. The silyl group is attached via a stable urea linkage and a propyl spacer.
