Hexamethyldisilane

Description:

Hexamethyldisilane (HMDS) is an organosilicon compound characterized by its chemical formula (CH₃)₆Si₂. It consists of two silicon atoms bonded to six methyl groups, making it a member of the silane family. This colorless, flammable liquid has a low viscosity and is known for its distinctive odor. HMDS is soluble in organic solvents but has limited solubility in water. It is primarily used as a precursor in the production of silicon-based materials, including coatings and thin films, and serves as a reagent in various chemical reactions, particularly in the field of organosilicon chemistry. Additionally, HMDS is utilized in semiconductor manufacturing for surface modification and as a protective agent against moisture. Its volatility and reactivity make it an important compound in both industrial and laboratory settings. Safety precautions are necessary when handling HMDS due to its flammability and potential health hazards upon inhalation or skin contact.
