描述
2-furancarboxaldehyde, also known as furaldehyde or 2-formylfuran, is a member of the class of compounds known as aryl-aldehydes. Aryl-aldehydes are compounds containing an aldehyde group directly attached to an aromatic ring. 2-furancarboxaldehyde is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2-furancarboxaldehyde is a sweet, almond, and baked tasting compound and can be found in a number of food items such as coriander, cocoa bean, red raspberry, and rice, which makes 2-furancarboxaldehyde a potential biomarker for the consumption of these food products. 2-furancarboxaldehyde can be found primarily in feces and urine. 2-furancarboxaldehyde exists in all eukaryotes, ranging from yeast to humans.
