CAS 25498-02-6: Silicic acid, methyl ester

Description: Silicic acid, methyl ester, with the CAS number 25498-02-6, is an organosilicon compound characterized by the presence of silicon, oxygen, and carbon atoms. It typically appears as a colorless to pale yellow liquid and is known for its low viscosity and volatility. This compound is a derivative of silicic acid, where the hydroxyl groups are replaced by methoxy groups, enhancing its solubility in organic solvents. Silicic acid, methyl ester exhibits properties such as hydrophobicity and the ability to form siloxane bonds, making it useful in various applications, including as a coupling agent, surface modifier, and in the formulation of coatings and adhesives. Additionally, it can play a role in the synthesis of more complex organosilicon compounds. Its reactivity is influenced by the presence of the methoxy groups, which can undergo hydrolysis in the presence of water, reverting to silicic acid. Safety data should be consulted for handling and exposure guidelines, as with all chemical substances.
