Chemical Information
FooDB Name2-Hydroxybenzaldehyde
DescriptionSalicyladehyde or 2-Hydroxybenzaldehyde, also known as salicylal or o-formylphenol, belongs to the class of organic compounds known as hydroxybenzaldehydes. These are organic aromatic compounds containing a benzene ring carrying an aldehyde group and a hydroxyl group. Salicylaldehyde is a colorless oily liquid. At high concentrations it has a bitter almond odor. In nature, salicylaldehyde has been identified as the metabolite responsible for the characteristic aroma of buckwheat (PMID: 26003350). It is also a component of castoreum, used in perfumery (PMID: 24249178). The defensive secretions of some leaf beatle species, such as the red poplar leaf beetle, also contain salicylaldehyde (PMID: 27033853).
