  <name>4-Ethylbenzaldehyde</name>
  <description>4-Ethylbenzaldehyde, also known as benzaldehyde,4-ethyl or EBAL, belongs to the class of organic compounds known as benzoyl derivatives. These are organic compounds containing an acyl moiety of benzoic acid with the formula (C6H5CO-). 4-Ethylbenzaldehyde is a neutral compound. 4-Ethylbenzaldehyde is a colorless to pale yellow clear liquid with a bitter almond, sweet, anise, cherry odor (http://www.thegoodscentscompany.com/data/rw1038111.html#toorgano). 4-Ethylbenzaldehyde has been in alcoholic beverages, nuts, and tea. This could make 4-ethylbenzaldehyde a potential biomarker for the consumption of these foods. 4-Ethylbenzaldehye is a derivative of benzaldehyde. As a volatile component 4-ethylbenzaldehyde is found in plants such as Z. mays (https://doi.org/10.1007/s11356-017-0140-x).</description>
