2,2-Bis-(4-methyl-diphenyl-siloxy-phenyl)-propan, also known as bis(4-methyldiphenylsilyl)propane, is an organosilicon compound characterized by its molecular formula C27H28OSi2. 2,2-Bis-(4-methyl-diphenyl-siloxy-phenyl)-propan features a propane backbone with two 4-methyldiphenylsilyl groups attached to the terminal carbon atoms. The 4-methyldiphenylsilyl groups consist of a silicon atom bonded to two phenyl rings and a methyl group, with an oxygen atom connecting the silicon to the propane chain. This structure endows the compound with unique properties, such as thermal stability and resistance to hydrolysis, making it potentially useful in various applications, including as a precursor in the synthesis of other organosilicon compounds or as a component in specialty materials.
The CAS Registry Mumber 4520-37-0 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 7 respectively. Calculate Digit Verification of CAS Registry Number 4520-37: (6*4)+(5*5)+(4*2)+(3*0)+(2*3)+(1*7)=70 70 % 10 = 0 So 4520-37-0 is a valid CAS Registry Number.
