Perfluoroglutaric acid diphenyl ester, also known as PFDA-DPE, is a perfluorinated organic compound characterized by its unique chemical structure. It is derived from perfluoroglutaric acid, where two of the carboxylic acid groups are esterified with phenol, resulting in a molecule with the formula C20H8F13O4. Perfluorglutarsaeure-diphenylester is part of a class of chemicals known as perfluoroalkyl and polyfluoroalkyl substances (PFAS), which are widely used in various industrial and consumer applications due to their resistance to heat, water, and oil. PFDA-DPE, in particular, may be used in the production of high-performance polymers and as a precursor in the synthesis of other perfluorinated compounds. However, due to the persistence and potential health risks associated with PFAS, there is growing concern about their environmental and human health impacts, leading to increased scrutiny and regulation of these chemicals.
The CAS Registry Mumber 2193-22-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 3 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2193-22: (6*2)+(5*1)+(4*9)+(3*3)+(2*2)+(1*2)=68 68 % 10 = 8 So 2193-22-8 is a valid CAS Registry Number.
