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). 2-Formylphenol FEMA 3004 O-formylphenol O-hydroxybenzaldehyde Salicylal Salicylaldehyd Salicylaldehyde Salicylaldehyde, 8CI Salicylic aldehyde Salizylaldehyd C7H6O2 122.1213 122.036779436 2-hydroxybenzaldehyde salicylaldehyde 90-02-8 OC1=CC=CC=C1C=O InChI=1S/C7H6O2/c8-5-6-3-1-2-4-7(6)9/h1-5,9H SMQUZDBALVYZAC-UHFFFAOYSA-N belongs to the class of organic compounds known as hydroxybenzaldehydes.
