Used primarily as a reagent in organosilicon chemistry, this compound serves as a source of silyl groups in the synthesis of complex silicon-containing molecules. Its steric bulk and stability make it suitable for controlled silicon–silicon bond formation in specialized catalytic and materials science applications. It is also employed in the preparation of precursors for silicon-based polymers and in the development of silicon thin films through thermal decomposition processes. Due to the presence of phenyl and methyl substituents, it contributes to enhanced solubility and handling in nonpolar solvents, facilitating its use in laboratory-scale organic and organometallic transformations.
