Toluene-4-sulfonic acid-(2,2,3,3,4,4,4-heptafluoro-1-heptafluoropropyl-butyl ester) is a complex organic compound with the chemical formula C16H12F14O4S. It is an ester derivative of toluene-4-sulfonic acid, where the hydroxyl group is replaced by a heptafluoropropyl-butyl group. toluene-4-sulfonic acid-(2,2,3,3,4,4,4-heptafluoro-1-heptafluoropropyl-butyl ester) is characterized by its fluorinated chain, which imparts unique properties such as increased lipophilicity and resistance to hydrolysis. It is often used in the synthesis of pharmaceuticals and other specialty chemicals due to its ability to enhance the solubility and bioavailability of certain drugs. The compound's structure also makes it a potential candidate for applications in materials science, where its fluorinated nature could influence the material's surface properties and chemical stability.
The CAS Registry Mumber 564-17-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 4 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 564-17: (5*5)+(4*6)+(3*4)+(2*1)+(1*7)=70 70 % 10 = 0 So 564-17-0 is a valid CAS Registry Number.
