Chloromethyl Trimethoxysilane: Properties, Applications, and Innovations

Silane compounds are widely used in various industries, such as pharmaceuticals, coatings, adhesives, and paints. One of the most versatile silane compounds is chloromethyl trimethoxysilane, also known as Monochloromethyltrimethoxysilane, (Chloromethyl)(trimethoxy)silane, (Chloromethyl)trimethoxysilane, Chloromethyltrimethoxysilane, and chloromethyl(trimethoxy)silane. This article will focus on the properties, applications, and innovations of this important silane compound, with a special emphasis on Inno Specialty Chemicals, the leading manufacturer and supplier of this product from China.

Properties of Chloromethyl Trimethoxysilane

Chloromethyl trimethoxysilane is a colorless to pale yellow liquid with a pungent odor. Its molecular formula is C5H12ClO3Si, and its molecular weight is 198.69 g/mol. This silane compound has a boiling point of 109-111 °C, a flash point of 33 °C, and a density of 1.069 g/cm3 at 25 °C. It is soluble in most organic solvents, such as ethanol, acetone, and benzene, and reacts with water to form hydrochloric acid and trimethoxysilanol.

The chemical structure of chloromethyl trimethoxysilane consists of a silicon atom bonded to three methoxy groups (-OCH3) and a chloromethyl group (-CH2Cl). This unique structure makes it a versatile silane coupling agent that can improve the adhesion, wetting, and dispersion of various organic and inorganic substrates. Chloromethyl trimethoxysilane can also be used as a precursor for various functionalized silanes, such as amino, epoxy, and mercapto silanes, which can further enhance the properties of coatings, adhesives, and composites.
