Applications

It is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and Dyestuff. It is also used as a desilylating agent. It is also been used in the protodesilylation of the phenyl group as part of the conversion of the dimethylphenylsilyl group into a hydroxyl group with retention of configuration.

Notes

Keep container tightly closed in a dry and well-ventilated place. Store under inert gas. Stable, but moisture sensitive. Incompatible with water, moist air, metals, strong oxidizing agents. Store under dry atmosphere.
