Dimethyldichlorosilane (CAS No. 5577-70-8) is a colorless liquid with a boiling point of 66.7 °C and a melting point of -126 °C. It has a molecular weight of 146.04 and a chemical formula of C2H6Cl2Si. It has a vapor pressure of 0.41 mmHg (20 °C) and a vapor density of 3.46 (Air = 1). It is insoluble in water and is stable under normal temperatures and pressures.

Dimethyldichlorosilane is primarily used in the chemical industry as a precursor for silicone polymers and silicone oils. It is also used as an intermediate in the production of organosilicon compounds, such as dimethyldichlorosilane, which can be used as a vulcanizing agent in the rubber industry. It is also used as a dehydrating agent and an intermediate in the production of organosilicon compounds.

Dimethyldichlorosilane is highly flammable and should be handled with extreme caution. It should be stored in a cool, dry, and well-ventilated area away from sources of ignition. It should be kept away from oxidizing agents, bases, metals, and alkalis. It should also be kept away from incompatible materials such as acids, organic materials, and water. Protective gloves and other personal protective equipment should be worn when handling Dimethyldichlorosilane.
