Potassium 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11-icosafluoroundecanoate is a complex chemical compound with the molecular formula C11HF21KO2. It is a fluorinated derivative of undecanedioic acid, where 18 of the 22 hydrogen atoms have been replaced by fluorine atoms. potassium 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11-icosafluoroundecanoate is an ionic salt, consisting of a potassium cation (K+) and a perfluoroundecanoate anion (C11F21COO-). It is known for its unique properties, such as high thermal stability, low surface tension, and excellent chemical resistance, which make it useful in various industrial applications, including as a surfactant, lubricant, or in the production of specialty polymers. Due to its highly fluorinated nature, it also exhibits interesting physical and chemical behaviors that are distinct from its hydrocarbon counterparts.
The CAS Registry Mumber 307-71-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 7 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 307-71: (5*3)+(4*0)+(3*7)+(2*7)+(1*1)=51 51 % 10 = 1 So 307-71-1 is a valid CAS Registry Number.
