Application

1,4-Bis(trimethylsilyl)benzene (TMSB) can be used:
  • As a precursor for developing silicon carbide coating using plasma-assisted chemical vapor deposition (CVD) process.
  • As a secondary standard in quantitative NMR (qNMR) spectroscopy.
  • As an internal standard for quantitation of small organic molecules in DMSO-d6 solution by 1H NMR spectroscopy.

Standards are required in quantitative NMR (qNMR) to obtain accurate and precise results. In this study acetanilide was established and used as a primary standard. Six other chemicals were selected as secondary standards: 3,4,5-trichloropyridine, dimethylterephthalate, maleic acid, 3-sulfolene, 1,4-bis(trimethylsilyl)benzene, and
