SiSiB® PC5620 is a clear, colourless to yellowish, pungent smelling, caustic and flammable liquid. It can be dissolved in non-protonating solvents without decomposition.
Color and Appearance
Colorless transparent liquid
SiSiB® PC5620 organofunctional silanes may used as silylating agent for dervatization of primary and secondary alcohols etc.
The hydrolytic stability of the trimethylsilyl-protected alcohols lies between that of methyldiisopropylsilyl- and trimethylsilyl-protected alcohols in acid and base. The selective oxidation of the triethylsilyl-protected alcohols in the presence of tert-butyldimethylsilyl-protected alcohol has been shown. The deprotection of silyl ethers has been reviewed as has the oxidation of silyl ethers.
SiSiB® PC5620 may be used to protect allylic esters as silylketene acetal. It is more stable but less volatile derivates than trimethylchlorosilane.
SiSiB® PC5620 chlorosilane is supplied in 180Kg steel drum.
In the unopened original container SiSiB® PC5620 has a shelf life of one year in a dry and cool place.
