4-Formyl-p-quarterphenyl, also known as 4-formyl-4'-biphenyl, is an organic compound with the chemical formula C13H10O. It is a derivative of biphenyl, featuring a formyl group (-CHO) attached to the 4-position of one of the benzene rings. 4-Formyl-p-quarterphenyl is characterized by its molecular structure, which consists of two phenyl rings connected by a single bond, with the formyl group present on one of the rings. 4-Formyl-p-quarterphenyl is a white crystalline solid and is used as an intermediate in the synthesis of various organic compounds, including pharmaceuticals and dyes. It is typically synthesized through the Friedel-Crafts acylation of biphenyl with acetyl chloride in the presence of a Lewis acid catalyst. Due to its reactivity, it is important to handle 4-Formyl-p-quarterphenyl with care, as it may undergo further reactions, such as oxidation or condensation, under certain conditions.
The CAS Registry Mumber 3365-15-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,6 and 5 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3365-15: (6*3)+(5*3)+(4*6)+(3*5)+(2*1)+(1*5)=79 79 % 10 = 9 So 3365-15-9 is a valid CAS Registry Number.
