Methyltrimethoxysilane
Manufactured by Merck Group
Sourced in United States, Germany
Methyltrimethoxysilane is a chemical compound used as a precursor in the synthesis of various silicone-based materials. It is a clear, colorless liquid with a characteristic odor. The primary function of methyltrimethoxysilane is to serve as a building block in the production of silicone polymers and other silicone-containing materials.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
