Common Name | 1H-Pyrrole-2-carboxaldehyde |
---|
Description | 1H-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 ethereal tasting compound. 1H-Pyrrole-2-carboxaldehyde is found, on average, in the highest concentration within beer. 1H-Pyrrole-2-carboxaldehyde has also been detected, but not quantified in, several different foods, such as teas (Camellia sinensis), blackberries (Rubus), asparagus (Asparagus officinalis), pulses, and evergreen blackberries (Rubus laciniatus). This could make 1H-pyrrole-2-carboxaldehyde a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 1H-Pyrrole-2-carboxaldehyde. |
