Metabolite Identification
Common NameSalicylic acid
DescriptionSalicylic acid, also known as ionil or 2-carboxyphenol, belongs to the class of organic compounds known as salicylic acids. These are ortho-hydroxylated benzoic acids. Salicylic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Salicylic acid exists in all living species, ranging from bacteria to humans. Salicylic acid is a potentially toxic compound.
