Chemical Information
FooDB Name1H-Pyrrole-2-carboxaldehyde
Description1H-Pyrrole-2-carboxaldehyde, also known as alpha-pyrrolaldehyde or 2-carboxaldehyde-1H-pyrrole, belongs to the class of organic compounds known as aryl-aldehydes. Aryl-aldehydes are compounds containing an aldehyde group directly attached to an aromatic ring. 1H-Pyrrole-2-carboxaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). 1H-Pyrrole-2-carboxaldehyde is an ethereal tasting compound. 1H-Pyrrole-2-carboxaldehyde has been detected, but not quantified in, several different foods, such as asparagus, coffee and coffee products, evergreen blackberries, pulses, and tea. This could make 1H-pyrrole-2-carboxaldehyde a potential biomarker for the consumption of these foods.
