Bis(4-biphenylyl)tetraacetylen, also known as 1,4-bis(4-ethynylphenyl)benzene, is an organic compound characterized by its unique structure. It features a central benzene ring with two 4-biphenylyl groups attached to it via ethynyl (acetylenic) linkages. This molecule is of interest in materials science and chemistry due to its potential applications in the synthesis of conjugated polymers and organic electronics. The ethynyl groups allow for the formation of extended π-conjugated systems, which can influence the electronic and optical properties of the material. Bis(4-biphenylyl)tetraacetylen is a precursor in the preparation of more complex molecular structures and is studied for its role in creating materials with specific electronic properties, such as semiconducting polymers used in solar cells and light-emitting diodes.

7642-37-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7642-37-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.Calculate Digit Verification of CAS Registry Number 7642-37:
(6*7)+(5*6)+(4*4)+(3*2)+(2*3)+(1*7)=107
107 % 10 = 7
So 7642-37-7 is a valid CAS Registry Number.
