Product introduction

YAC-TECS is a clear, colourless to yellowish, pungent smelling, caustic and flammable liquid. It can be dissolved in non-protonating solvents without decomposition.


YAC-TECS 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.

YAC-TECS may be used to protect allylic esters as silylketene acetal. It is more stable but less volatile derivates than trimethylchlorosilane.

Packing and Storage

YAC-TECS chlorosilane is supplied in 180Kg steel drum.

In the unopened original container YAC-TECS has a shelf life of one year in a dry and cool place.
