Benzaldehyde (C6H5CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is among the simplest aromatic aldehydes and one of the most industrially useful.

It is a colorless liquid with a characteristic almond-like odor, and is commonly used in cherry-flavored sodas.[5] A component of bitter almond oil, benzaldehyde can be extracted from a number of other natural sources.[6] Synthetic benzaldehyde is the flavoring agent in imitation almond extract, which is used to flavor cakes and other baked goods.[7]
