| Common Name | 4-Ethylbenzaldehyde |
|---|
| Description | 4-Ethylbenzaldehyde 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 sweet, almond, and bitter tasting compound. 4-Ethylbenzaldehyde has been detected, but not quantified in, several different foods, such as green tea, teas (Camellia sinensis), nuts, black tea, and herbal tea. This could make 4-ethylbenzaldehyde a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on 4-Ethylbenzaldehyde. |
