Pentafluoroethyl alcohol, also known as 2,2,2-trifluoro-1-hydroxyethane or CF3CF2CH2OH, is an organofluorine compound characterized by the presence of five fluorine atoms attached to an ethyl alcohol backbone. This unique structure endows it with exceptional chemical and physical properties, such as high thermal stability, low surface tension, and resistance to hydrolysis. Due to these characteristics, pentafluoroethyl alcohol finds applications in various industries, including pharmaceuticals, as a solvent in organic synthesis, and as a component in the production of fluoropolymers. Its synthesis typically involves the reaction of vinylidene fluoride with hydrogen fluoride, followed by hydrolysis to yield the alcohol. The compound's reactivity and stability make it a valuable intermediate in the preparation of other fluorinated compounds.
The CAS Registry Mumber 7057-80-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,5 and 7 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 7057-80: (6*7)+(5*0)+(4*5)+(3*7)+(2*8)+(1*0)=99 99 % 10 = 9 So 7057-80-9 is a valid CAS Registry Number.
