China High Purity Best Price 5n C4h12si (4MS) C4h12si Tetramethylsilane

Product Description

C4H12Si is the chemical formula for a compound called tetramethylsilane (TMS). Here's some information about it:

1. Structure: Tetramethylsilane (TMS) consists of a central silicon (Si) atom bonded to four methyl (CH3) groups. The molecule has a tetrahedral arrangement, with each methyl group positioned around the silicon atom.

2. Properties: TMS is a colorless liquid with a relatively low boiling point of around 26 degrees Celsius (79 degrees Fahrenheit). It has a relatively high vapor pressure and is highly flammable.

3. Uses:

   • NMR spectroscopy: TMS is primarily usedin nuclear magnetic resonance (NMR) spectroscopy as a reference standard. It is added to samples in NMR experiments to provide a known reference signal at a specific chemical shift (0 ppm) in the spectrum. This allows researchers to calibrate their NMR measurements and determine the chemical shifts of other compounds accurately.
   • Chemical synthesis: TMS can be used as a reactant or a protecting group in organic synthesis. It can participate in various reactions, such as hydrosilylation and cross-coupling reactions, to introduce a silicon-containing group into organic molecules.
   • Solvent: TMS is used as a solvent or diluent for certain reactions or processes, particularly in the field of silicon chemistry.

4. Safety considerations: TMS is flammable and should be handled with caution. It should be stored and used in well-ventilated areas away from ignition sources. Like any other chemical, proper safety procedures should be followed when handling TMS, including the use of appropriate protective equipment.
