2,5-bis-(2-hydroxy-anilino)-terephthalic acid dimethyl ester is a complex organic compound with the chemical formula C20H20N2O6. It is a derivative of terephthalic acid, featuring two hydroxyanilino groups attached at the 2,5-positions. The dimethyl ester form indicates that the carboxylic acid groups have been esterified with methanol, resulting in a more stable and less reactive compound. This chemical is known for its potential applications in the synthesis of dyes, pharmaceuticals, and other specialty chemicals. Its structure provides a foundation for the development of materials with specific optical and electronic properties, making it a subject of interest in materials science and chemical engineering.
The CAS Registry Mumber 5870-64-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,7 and 0 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5870-64: (6*5)+(5*8)+(4*7)+(3*0)+(2*6)+(1*4)=114 114 % 10 = 4 So 5870-64-4 is a valid CAS Registry Number.
