76328-77-3 Usage
General Description
N-Octadecyldimethyl(dimethylamin)silane is a chemical compound that belongs to the class of silanes, which are molecules that contain a silicon atom attached to carbon and hydrogen atoms. This specific silane compound has a long carbon chain (octadecyl) and two dimethyl groups attached to a silicon atom. It is commonly used as a surface modifier in various industrial applications, including as a coating agent for surfaces such as glass, metal, and plastic. This chemical is known for its ability to enhance adhesion properties and improve the wetting behavior of surfaces, making it useful in adhesives, sealants, and coatings. Furthermore, its amphiphilic nature allows it to provide both hydrophobic and hydrophilic properties to surfaces, making it versatile for various surface modification purposes.
Check Digit Verification of cas no
The CAS Registry Mumber 76328-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,2 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76328-77:
(7*7)+(6*6)+(5*3)+(4*2)+(3*8)+(2*7)+(1*7)=153
153 % 10 = 3
So 76328-77-3 is a valid CAS Registry Number.

246. Monofunctional (Dimethylamino)silane as Silylating Agent

The reaction of triorganyl(dimethylamino)silanes with surface-hydrated silicon dioxide has been studied.These silylating agents are easy to prepare from the corresponding chloro or bromosilanes with dimethylamine.The resulting products are thermally stable and relatively volatile.Reaction with surface-hydrated silicon-dioxide preparations at a50-250 deg C for 170 h yields a dense grafted layer.However, with (dimethylamino)silanes having strongly polar substituents, a retreatment of the surface-modified silica seems to be necessary in order to attain maximum coverage.
