| Common Name | Acetoxyacetone |
|---|
| Description | Acetoxyacetone belongs to the class of organic compounds known as alpha-acyloxy ketones. These are ketones that have an acyloxy substituent alpha to the carbonyl group. They have the general structure R4C(=O)OC(R2)(R3)C(R1)=O (R1=organyl, R4=H or organyl; R2,R3 = any atom). Acetoxyacetone is a buttery and fruity tasting compound. Acetoxyacetone has been detected, but not quantified in, pineapples (Ananas comosus). This could make acetoxyacetone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Acetoxyacetone. |
