4-Triphenylsilyl-benzolsulfonsaeure, also known as 4-triphenylsilylbenzenesulfonic acid, is an organosilicon compound characterized by the presence of a triphenylsilyl group attached to a benzene ring, which is further functionalized with a sulfonic acid group at the para position. 4-Triphenylsilyl-benzolsulfonsaeure is of interest in organic synthesis and materials science due to its unique combination of aromatic, silyl, and sulfonic acid functionalities. The triphenylsilyl group provides steric bulk and can influence the reactivity and solubility of the molecule, while the sulfonic acid group imparts acidity and potential for further functionalization. The compound can be used as a building block in the synthesis of more complex organic molecules, particularly those requiring a stable silyl protecting group or a strong electron-withdrawing sulfonic acid group. Its applications may extend to the development of new materials, pharmaceuticals, and other specialty chemicals.
The CAS Registry Mumber 1833-35-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 3 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1833-35: (6*1)+(5*8)+(4*3)+(3*3)+(2*3)+(1*5)=78 78 % 10 = 8 So 1833-35-8 is a valid CAS Registry Number.
