Tetramethylsilane is widely used as a reference standard in nuclear magnetic resonance (NMR) spectroscopy due to its sharp and easily identifiable signal. It serves as a calibration point for chemical shift measurements, particularly in proton NMR, ensuring accurate and consistent results in the analysis of organic compounds. Additionally, it is employed as a solvent in various chemical reactions and as a precursor in the synthesis of silicone-based materials. Its non-reactive nature and volatility make it suitable for applications in research and industrial processes where inert and easily removable substances are required.
