Alfa Aesar™ Methyltrichlorosilane, 97%

Description

Applications
Methyltrichlorosilane is used in production of methyl silicone resins, its vapor reacts with water on surfaces to give a thin layer of methylpolysiloxane which make it a water-repellent film. A combination of methyltrichlorosilane and sodium iodide can be used to cleave carbon-oxygen bonds such as methyl ethers. It is used as a precursor for forming various cross-linked siloxane polymers. Trichloromethylsilane is the starting material for the production of pure silicon for manufacture of semiconductors and optical fibers.

Solubility
Reacts with water.

Notes
Moisture sensitive. Store away from oxidizing agents, water/ moisture.
