Trisiloxane, 1,1,3,3,5,5-hexamethyl-1,5-bis(pentafluorophenyl)-, also known as PFOTES, is a complex organosilicon compound characterized by its unique structure. It consists of a trisiloxane backbone, which is a chain of three silicon atoms connected by oxygen atoms, with each silicon atom bonded to three methyl groups. The compound is further distinguished by the presence of two pentafluorophenyl groups attached to the terminal silicon atoms. This specific arrangement endows PFOTES with unique properties, making it a valuable component in various applications, such as in the production of high-performance polymers and as a precursor in the synthesis of other organosilicon compounds. Its stability, thermal resistance, and chemical inertness are some of the key attributes that make it suitable for these uses.

20494-17-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20494-17-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,9 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.Calculate Digit Verification of CAS Registry Number 20494-17:
(7*2)+(6*0)+(5*4)+(4*9)+(3*4)+(2*1)+(1*7)=91
91 % 10 = 1
So 20494-17-1 is a valid CAS Registry Number.
