Benzoic acid, 5-formyl-2-hydroxy-3-methoxy-, ethyl ester, also known as ethyl vanillin, is a synthetic organic compound that serves as a key flavoring agent in the food and beverage industry. It is an ester derivative of vanillin, the primary component responsible for the characteristic aroma and taste of vanilla. Ethyl vanillin is produced through a chemical synthesis process, which involves the esterification of 5-formyl-2-hydroxy-3-methoxybenzoic acid with ethanol. Benzoic acid, 5-formyl-2-hydroxy-3-methoxy-, ethyl ester is widely used as a cost-effective and stable alternative to natural vanilla extract, offering a similar flavor profile but with a more consistent and intense taste. It is also employed in the production of perfumes and pharmaceuticals due to its pleasant odor and versatility in chemical reactions.
The CAS Registry Mumber 3517-02-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,1 and 7 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3517-02: (6*3)+(5*5)+(4*1)+(3*7)+(2*0)+(1*2)=70 70 % 10 = 0 So 3517-02-0 is a valid CAS Registry Number.
