1,1,6,6-Tetrakis-(4-methoxyphenyl)-hexa-1,2,3,5-tetraen, also known as tetramesic acid, is a chemical compound with the molecular formula C28H24O8. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and acetone. 1,1,6,6-Tetrakis-(4-methoxyphenyl)-hexa-1,2,3,5-tetraen is characterized by its unique structure, featuring a central hexa-1,2,3,5-tetraen core with four 4-methoxyphenyl groups attached to the 1,1,6,6 positions. Tetramesic acid is an important intermediate in the synthesis of various organic compounds, particularly in the production of dyes and pigments. It is also used as a reagent in analytical chemistry for the detection of certain metal ions. Due to its sensitivity to light and heat, it is typically stored in a cool, dark place to maintain its stability.
The CAS Registry Mumber 1674-23-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 4 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1674-23: (6*1)+(5*6)+(4*7)+(3*4)+(2*2)+(1*3)=83 83 % 10 = 3 So 1674-23-3 is a valid CAS Registry Number.
