1,3-Bis-(dimethyl-butylsiloxy)-benzol, also known as 1,3-bis(dimethylbutylsiloxy)benzene, is an organosilicon compound characterized by its benzene ring with two dimethylbutylsiloxy groups attached at the 1 and 3 positions. 1,3-Bis-(dimethyl-butylsiloxy)-benzol is a type of silyl ether, which is a derivative of benzene where the hydroxyl groups are replaced by silyl groups. It is used in various applications, including as a coupling agent in the synthesis of organic compounds, a stabilizer in polymer chemistry, and a reagent in the preparation of other organosilicon compounds. The presence of the dimethylbutyl groups provides steric hindrance and can influence the compound's reactivity and solubility properties.
The CAS Registry Mumber 4520-33-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,2 and 0 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4520-33: (6*4)+(5*5)+(4*2)+(3*0)+(2*3)+(1*3)=66 66 % 10 = 6 So 4520-33-6 is a valid CAS Registry Number.
