General Description
TRIS(DIMETHYLAMINO)PHENYLSILANE is an organosilicon compound that consists of a silicon atom attached to three dimethylamino groups and a phenyl group. It is commonly used as a precursor in the synthesis of silicon-containing materials, such as silicon-based polymers, ceramics, and thin films. This chemical is highly reactive and can undergo various chemical reactions, including hydrosilylation and cross-coupling reactions, making it valuable in the field of organic and materials chemistry. Additionally, TRIS(DIMETHYLAMINO)PHENYLSILANE is known for its ability to form stable and uniform thin films, making it suitable for applications in electronics, optics, and surface coatings. As a result, it is considered an important building block for the preparation of advanced materials with diverse industrial and technological applications.
Check Digit Verification of cas no
The CAS Registry Mumber 4840-75-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4840-75:
(6*4)+(5*8)+(4*4)+(3*0)+(2*7)+(1*5)=99
99 % 10 = 9
So 4840-75-9 is a valid CAS Registry Number.

Chloraminosilanes II. Preparation and spectroscopic studies on alkyl-(dimethylamino)chlorosilanes
Washburne,Peterson Jr.

Several new compounds containing both chloro and dimethylamino groups linked to silicon have been prepared. The general method involved reacting a solution of the appropriate polychlorosilane in ether at ca. - 50° with a chilled ethereal solution of dimethylamine. Prepared in this fashion were CH3Si(NMe2)Cl2, CH3Si(NMe2)2-Cl, PhSi(NMe2)Cl2, PhSi(NMe2)2Cl, CH3(H)Si(NMe2)Cl, (CH3)2Si(NMe2)Cl, CH2CH(CH3)Si(NMe2)Cl, and Ph2Si(NMe2)Cl. Comparison of the spectra of these compounds with those in the perhalo and peramine series showed that replacement of NMe2 for Cl resulted in an upfield shift of the resonances of the other groups linked to silicon, a shift which parallels that observed upon substitution of CH3 for Cl. The relationship of ν(SiH) in the IR and δ(SiH) in the NMR spectra was linear.
