2,2,3,3-Tetramethyltetrasilane - Introduction

2,2,3,3-tetramethyltetrasilane, also known as Tetramethylsilane (TMS), is an organosilicon compound. The following is a description of the relevant properties, uses, methods and safety information:

Nature:
-Appearance: colorless liquid
-Molecular formula: C4H12Si4
-Molecular weight: 176.41g/mol
-Boiling Point: 26-27°C
-Density: 0.75g/cm³

Use:
-Standard compound: TMS is commonly used as an internal standard substance in nuclear magnetic resonance (NMR) analysis. It produces clear peaks in the NMR spectrum and does not interfere with the signal of the measured substance, so it is widely used in this field.
-Solvent: TMS can also be used as a solvent in organic synthesis.
-Gas chromatography (GC) calibration substance: Because TMS has good volatility and stability, it can be used as a calibration agent for internal standard substances during GC analysis.

Preparation Method:
The preparation of TMS is usually achieved by an ethylation reaction. One commonly used method is the reaction of trichlorosilane with methyllithium to produce TMS and lithium chloride.

Safety Information:
TMS is generally considered to be a low-toxic compound and less harmful to the human body. But as an organic compound, still need to pay attention to the following safety matters:
-Avoid contact with skin and eyes, and wear appropriate protective equipment when using;
-Avoid inhaling its vapor and keep it well ventilated during use;
-Store away from fire and oxidant to avoid fire or explosion;
-When using and storing, please follow all applicable safety procedures and guidelines for their proper handling.
