1,1,2,2-Tetrakis-(2,6-dimethyl-phenyl)-ethane, also known as tetraphenylethylene or TPE, is an organic compound with the chemical formula C34H34. It is a symmetrical molecule consisting of an ethane core with four phenyl groups attached to each carbon atom, where each phenyl group has two methyl groups at the 2 and 6 positions. TPE is a colorless, crystalline solid with a melting point of 195-198°C. It is known for its unique photophysical properties, such as strong fluorescence and photostability, making it a valuable compound in various applications, including organic light-emitting diodes (OLEDs), sensors, and as a building block for more complex molecular structures. TPE's chemical stability and low toxicity also contribute to its wide range of uses in research and industry.

6857-67-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6857-67-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,5 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.Calculate Digit Verification of CAS Registry Number 6857-67:
(6*6)+(5*8)+(4*5)+(3*7)+(2*6)+(1*7)=136
136 % 10 = 6
So 6857-67-6 is a valid CAS Registry Number.
