It is a colorless to pale yellow liquid with a fruity odor. 3',4',5'-Triaethoxy-acetophenon is primarily used as a synthetic intermediate in the production of various pharmaceuticals, agrochemicals, and fragrances. It is synthesized through the Friedel-Crafts acylation of 1,2,3-triethoxybenzene with acetyl chloride in the presence of a Lewis acid catalyst, such as aluminum chloride. Due to its reactivity and potential applications, 3',4',5'-triethoxy-acetophenon is an important chemical in the field of organic synthesis.
The CAS Registry Mumber 1147-81-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 7 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1147-81: (6*1)+(5*1)+(4*4)+(3*7)+(2*8)+(1*1)=65 65 % 10 = 5 So 1147-81-5 is a valid CAS Registry Number.
