Application
Tetramethylsilane can be used as:
- A precursor to synthesize α-SiC by chemical vapor deposition.
- A reactant to synthesize 1,3,5,7-tetramethyladamantane from adamantane in the presence of aluminum chloride and dichloromethane.
- A solvent for the hydroaminomethylation of 1-octene with morpholine.
- A methylating reagent for the conversion of germanium tetrachloride to tetramethylgermanium, trimethylgermanium chloride, dimethylgermanium dichloride or methylgermanium trichloride.

E-cigarette aerosol emission studies typically focus on benchmarking toxicant levels versus those of cigarettes. However, such studies do not fully account for the distinct chemical makeup of e-liquids and their unique properties. These approaches often conclude that there are fewer

The chemical shift of TMS is commonly assumed to be zero. However, it varies by over 1 ppm for 1H and 4 ppm for 13C and shows a correlation with the physical properties of the solvent. Using the commonly accepted
