3,4,5-triphenylphenol is an organic compound characterized by its molecular formula C24H18O, featuring a phenol group (C6H5OH) with three phenyl rings (C6H5) attached to the 3rd, 4th, and 5th carbon atoms of the phenol's benzene ring. 3,4,5-triphenylphenol is known for its high stability and is often used in the synthesis of various pharmaceuticals, dyes, and polymers due to its unique structure and properties. It is typically synthesized through the Friedel-Crafts reaction, which involves the alkylation or acylation of phenol with benzene in the presence of a catalyst. 3,4,5-triphenylphenol is a white crystalline solid with limited solubility in water but is soluble in organic solvents such as ethanol and acetone. Its chemical properties include reactivity towards electrophilic substitution, making it a versatile building block in organic chemistry.
The CAS Registry Mumber 1731-37-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,3 and 1 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 1731-37: (6*1)+(5*7)+(4*3)+(3*1)+(2*3)+(1*7)=69 69 % 10 = 9 So 1731-37-9 is a valid CAS Registry Number.
