Trisilane, 1,1,1,3,3,3-hexamethyl-, also known as hexamethyltrisilane, is an organosilicon compound with the chemical formula (CH3)3SiSiSi(CH3)3. It is a colorless, volatile liquid that is insoluble in water but soluble in organic solvents. Trisilane, 1,1,1,3,3,3-hexamethyl- is primarily used as a coupling agent in the production of silicone rubber, silicone resins, and other silicone-based materials. It serves to improve the adhesion between the silicone and other materials, such as glass, metal, and plastic. Hexamethyltrisilane is also used as a silylating agent in organic synthesis and as a precursor in the production of other organosilicon compounds. Due to its flammability and potential health hazards, it is important to handle hexamethyltrisilane with caution and in accordance with safety regulations.

5089-32-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5089-32-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,8 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5089-32:
(6*5)+(5*0)+(4*8)+(3*9)+(2*3)+(1*2)=97
97 % 10 = 7
So 5089-32-7 is a valid CAS Registry Number.

Photolysis of tris(trimethylsilyl)silane: Trapping of sisyl radicals

Mohamed, Mustafa,Brook, Michael A.

, p. 1357 - 1362 (2007/10/03)

The photolysis of tris(trimethylsilyl)silane (TTMSS) was studied in the absence and in the presence of added trapping agents such as alkenes and alcohols. It was found that, unlike the case with pyrolysis, silyl radicals rather than silylenes are produced

Preparation of oligosilanes containing perhalogenated silyl groups (-SiX3, -SiX2-, >SiX-, X = Cl, Br) and their hydrogenation by stannanes

Herzog,Roewer

, p. 217 - 223 (2007/10/03)

Starting from methylphenylsubstituted oligosilanes the disilanes SiX3-SiXi,Me3-i (i = 0, 1, 2; X = Cl, Br), trisilanes SiX2(SiXiMe3-i) (i = 0, 1) and branched tetrasilanes SiX(SiXMe2)3 were synthesized and their behavior towards the Lewis-base catalyzed hydrogenation by stannanes was investigated. In the case of methylchlorodisilanes SiCl3-SiCliMe3-i Si-Si bond cleavage competes with the hydrogenation reaction.
