Metabolite Identification
Common Name6-Pentyl-2H-pyran-2-one
Description6-Pentyl-2H-pyran-2-one, also known as 6-pentylpyrone, belongs to the class of organic compounds known as pyranones and derivatives. Pyranones and derivatives are compounds containing a pyran ring which bears a ketone. 6-Pentyl-2H-pyran-2-one is an almond, coconut, and creamy tasting compound. 6-Pentyl-2H-pyran-2-one has been detected, but not quantified in, fruits. This could make 6-pentyl-2H-pyran-2-one a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 6-Pentyl-2H-pyran-2-one.
