1H,7H-Pyrazolo[1,2-a]pyrazole-2,3,5,6-tetracarboxylic acid, 7-methyl-1,1-diphenyl, tetramethyl ester is a complex organic compound with the molecular formula C22H20N2O8. It features a pyrazolo[1,2-a]pyrazole core structure, which is a fused ring system consisting of a pyrazole and a pyrazole ring. The compound is characterized by four carboxylic acid groups at positions 2, 3, 5, and 6, and a methyl group at the 7-position. The 1,1-diphenyl substituents are attached to the nitrogen atoms, and the tetramethyl ester groups are present, indicating that the carboxylic acid groups are esterified with methanol. 1H,7H-Pyrazolo[1,2-a]pyrazole-2,3,5,6-tetracarboxylic acid,
7-methyl-1,1-diphenyl-, tetramethyl ester is likely to be used in advanced chemical research or as a building block in the synthesis of more complex molecules, given its intricate structure and functional groups.
The CAS Registry Mumber 79558-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,5,5 and 8 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 79558-99: (7*7)+(6*9)+(5*5)+(4*5)+(3*8)+(2*9)+(1*9)=199 199 % 10 = 9 So 79558-99-9 is a valid CAS Registry Number.
