Metabolite Identification
Common Name3-Methoxysalicylic acid
Description3-Methoxysalicylic acid, also known as O-vanillic acid or O-vanillate, belongs to the class of organic compounds known as m-methoxybenzoic acids and derivatives. These are benzoic acids in which the hydrogen atom at position 3 of the benzene ring is replaced by a methoxy group. 3-Methoxysalicylic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 3-Methoxysalicylic acid has been detected, but not quantified in, evening primroses. This could make 3-methoxysalicylic acid a potential biomarker for the consumption of these foods. 3-Methoxysalicylic acid (CAS Number 877-22-5) is a beige fine crystalline powder.
