Description and Uses

Trimethoxy (methyl) silane is an organosilicon compound. It can be used as a crosslinker in the preparation of polysiloxane polymers. It can also be used as an acid scavenge used in the formation of substituted azulenes from allenylsilanes and tropyl?ium tetrafluoroborate. It can also be used as the precursor for synthesis of flexible silica aerogels.

Methyltrimethoxysilane is a reagent used in they synthesis of electronic materials and organometallic compounds. Used in the coating of carbon-fiber surfaces, as well as in the synthesis of nanocomposites.
