90162-40-6 Usage
General Description
1,4-bis(trimethylsiloxy)benzene, also known as tetramethyldisiloxane, is a chemical compound with the molecular formula C14H22O2Si2. It is a colorless liquid with a fruity odor and is commonly used as a crosslinker in the production of silicone polymers and resins. 1,4-bis(trimethylsiloxy)benzene is also utilized as a solvent and an intermediate in the synthesis of other chemicals. It is considered to be relatively safe for use, with low toxicity and environmental impact. However, precautions should be taken when handling 1,4-bis(trimethylsiloxy)benzene, and it should be stored and used according to proper safety guidelines to prevent any potential harmful effects.
Check Digit Verification of cas no
The CAS Registry Mumber 90162-40-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,6 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90162-40:
(7*9)+(6*0)+(5*1)+(4*6)+(3*2)+(2*4)+(1*0)=106
106 % 10 = 6
So 90162-40-6 is a valid CAS Registry Number.

Hierarchically porous monolithic silica with varying porosity using bis(trimethoxysilyl)arenes as precursors
Von Der Lehr, Martin,Ellinghaus, Rüdiger,Smarsly, Bernd M.
, p. 4455 - 4463 (2016/06/09)
The ortho-, meta- and para-isomers of bis(trimethoxysilyl)benzene and bis((trimethoxysilyl)phenyl)dimethoxysilane were synthesized from their corresponding diarylbromides. Mixtures of these bis(trimethoxysilyl)arenes and tetramethoxysilane (TMOS) were used as organosilica precursors for the preparation of macro-mesoporous silica monoliths using different amounts of the porogen poly(ethylene glycol) to investigate the effect on the porosity of the final materials. The prepared samples were characterized by nitrogen and dibromomethane sorption measurements, mercury intrusion porosimetry and scanning electron microscopy. The analysis of dibromomethane isotherms indicated a significantly lower polarity of the mesopore surface compared to that of pure SiO2 monoliths, proving the presence of arene units at the mesopore surfaces.
