1-Chlor-1-(pentafluorphenyl)-ethan, also known as 1-chloro-1-(pentafluorophenyl)ethane or CF3CF2C6H4Cl, is an organofluorine compound characterized by the presence of a chloroalkane functional group and a pentafluorophenyl moiety. This chemical features a chlorinated ethyl group (-CH2Cl) attached to a pentafluorophenyl ring, which consists of a benzene ring with five fluorine atoms. Due to its unique structure, 1-chloro-1-(pentafluorophenyl)ethane exhibits interesting properties, such as high chemical stability, low reactivity, and a strong electron-withdrawing effect from the fluorine atoms. These characteristics make it a potentially useful building block in the synthesis of various fluorinated organic compounds, pharmaceuticals, and materials with specific properties.
The CAS Registry Mumber 5576-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,7 and 6 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5576-26: (6*5)+(5*5)+(4*7)+(3*6)+(2*2)+(1*6)=111 111 % 10 = 1 So 5576-26-1 is a valid CAS Registry Number.
