Common Name | p-Coumaraldehyde |

Description | p-Coumaraldehyde (CAS: 2538-87-6), also known as 4-hydroxycinnamaldehyde or 3-(4-hydroxyphenyl)-2-propenal, belongs to the class of organic compounds known as cinnamaldehydes. These are organic aromatic compounds containing a cinnamlaldehyde moiety, consisting of a benzene and an aldehyde group to form 3-phenylprop-2-enal. p-Coumaraldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, p-coumaraldehyde has been detected, but not quantified in, several different foods, such as red rice, lindens, peaches, white lupines, and evergreen huckleberries. This could make p-coumaraldehyde a potential biomarker for the consumption of these foods. p-Coumaraldehyde is also a constituent of Alpinia galanga (greater galangal) rhizomes and Cucurbita maxima. |
