2,5-bis-(2-hydroxy-anilino)-terephthalic acid diethyl ester is a complex organic compound with the chemical formula C22H24N2O6. It is derived from terephthalic acid, a common dicarboxylic acid, and features two 2-hydroxy-anilino groups attached to the central terephthalic acid structure. The diethyl ester form indicates that the two carboxylic acid groups have been esterified with ethanol, resulting in a more stable and less reactive compound. This chemical is often used as an intermediate in the synthesis of various dyes and pigments, particularly those with high color strength and stability. Its molecular structure allows for the formation of strong intramolecular hydrogen bonds, which contribute to its thermal and chemical stability, making it a valuable component in the production of high-performance colorants.

5870-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5870-65-5 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 5 respectively.Calculate Digit Verification of CAS Registry Number 5870-65:
(6*5)+(5*8)+(4*7)+(3*0)+(2*6)+(1*5)=115
115 % 10 = 5
So 5870-65-5 is a valid CAS Registry Number.
