Note

Propanal, also known as N-propionaldehyde or C2H5CHO, belongs to the class of organic compounds known as alpha-hydrogen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. Propanal exists in all living species, ranging from bacteria to humans. Propanal is an alcohol, cocoa, and earthy tasting compound. Outside of the human body, Propanal is found, on average, in the highest concentration within wild celeries and carrots. Propanal has also been detected, but not quantified in several different foods, such as purple lavers, black salsifies, strawberry guava, grapefruit/pummelo hybrids, and alaska wild rhubarbs. It is an aldehyde that consists of ethane bearing a formyl substituent.
