33974-42-4 Usage
General Description
Triisopropylmethoxysilane is a colorless, flammable liquid chemical compound with the molecular formula C9H22O2Si. It is commonly used as a coupling agent in the production of silane-modified polymers and as a surface modifier in various industrial applications. Triisopropylmethoxysilane is known for its ability to form strong and stable bonds with both organic and inorganic materials, making it a valuable component in the production of adhesives, sealants, and coatings. Additionally, it is also used in the manufacturing of silicone rubber, resins, and composites due to its ability to improve surface adhesion and enhance the overall performance of the final product. However, it is important to handle triisopropylmethoxysilane with caution as it is highly reactive and can pose health hazards if not properly managed.
Check Digit Verification of cas no
The CAS Registry Mumber 33974-42-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,7 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33974-42:
(7*3)+(6*3)+(5*9)+(4*7)+(3*4)+(2*4)+(1*2)=134
134 % 10 = 4
So 33974-42-4 is a valid CAS Registry Number.

Versatile method for introduction of bulky substituents to alkoxychlorosilanes
Masaoka, Shin,Banno, Tadashi,Ishikawa, Mitsuo
, p. 182 - 192 (2007/10/03)
The reactions of various alkoxytrichlorosilanes prepared in situ from tetrachlorosilane and alcohols, with Grignard reagents bearing a bulky substituent such as the isopropyl, sec-butyl, and cyclohexyl group afforded triisopropyl-, tri(sec-butyl)-, and tricyclohexylalkoxysilane in high yields. The reactions of n-butoxytrichlorosilane with these Grignard reagents produced triisopropyl-, tri(sec-butyl)-, and tricyclohexyl(n-butoxy)silane in 94%, 96%, and 92% yields, respectively. Methoxymethyldichlorosilane reacted with the same Grignard reagents to give diisopropyl-, di(sec-butyl)-, and dicyclohexylmethoxymethylsilane in 84%, 83%, and 83% yields. Treatment of methoxydimethylchlorosilane with the Grignard reagents readily afforded isopropyl-, sec-butyl-, and cyclohexylmethoxydimethylsilane in excellent yields. Similar treatment of methoxydimethylchlorosilane with tert-butylmagnesium chloride gave tert-butylmethoxydimethylsilane in 62% yield.
