Metabolite Identification
Common Name2-Methylbenzaldehyde
Description2-Methylbenzaldehyde, also known as 2-formyltoluene or O-toluic aldehyde, belongs to the class of organic compounds known as benzoyl derivatives. These are organic compounds containing an acyl moiety of benzoic acid with the formula (C6H5CO-). 2-Methylbenzaldehyde exists in all living organisms, ranging from bacteria to humans. 2-Methylbenzaldehyde is a cherry tasting compound. 2-Methylbenzaldehyde is found, on average, in the highest concentration within soft-necked garlics (Allium sativum L. var. sativum). 2-Methylbenzaldehyde has also been detected, but not quantified in, several different foods, such as herbal tea, nuts, teas (Camellia sinensis), arabica coffees (Coffea arabica), and fruits. This could make 2-methylbenzaldehyde a potential biomarker for the consumption of these foods. 2-Methylbenzaldehyde is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on 2-Methylbenzaldehyde.
