| Common Name | 4'-Methylacetophenone |
|---|
| Description | 4'-Methylacetophenone, also known as melilot or sweet clover, belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. 4'-Methylacetophenone is a sweet, acetophenone, and bitter almond tasting compound. 4'-Methylacetophenone has been detected, but not quantified, in several different foods, such as citrus, garden tomato, pepper (spice), garden tomato (var.), and milk and milk products. This could make 4'-methylacetophenone a potential biomarker for the consumption of these foods. |
