2,4,6-trimethoxy-isophthalic acid dimethyl ester is a chemical compound with the molecular formula C12H16O8. It is a derivative of isophthalic acid, featuring three methoxy groups (-OCH3) attached to the 2, 4, and 6 positions of the isophthalic acid backbone. The dimethyl ester functional group is present, indicating that the two carboxylic acid groups have been esterified with methanol, resulting in the formation of two methyl ester groups (-COOCH3). 2,4,6-trimethoxy-isophthalic acid dimethyl ester is often used as an intermediate in the synthesis of various pharmaceuticals, dyes, and other organic compounds due to its versatile chemical structure. It is typically synthesized through the esterification of 2,4,6-trimethoxy-isophthalic acid with methanol in the presence of an acid catalyst. The compound is a white crystalline solid and is soluble in common organic solvents such as ethanol, acetone, and dichloromethane.
The CAS Registry Mumber 5071-59-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,7 and 1 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 5071-59: (6*5)+(5*0)+(4*7)+(3*1)+(2*5)+(1*9)=80 80 % 10 = 0 So 5071-59-0 is a valid CAS Registry Number.
