| Common Name | 5-Methoxysalicylic acid |
|---|
| Description | 5-methoxysalicylic acid is a methoxysalicylic acid that is salicylic acid which is carrying a methoxy group at position 5. It has a role as a bacterial metabolite and a human urinary metabolite. 5-Methoxysalicylic acid is also known as 2-hydroxy-5-methoxybenzoate or 5-methoxy-2-hydroxybenzoate and 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. Outside of the human body, 5-Methoxysalicylic acid has been detected, but not quantified in herbs and spices and tea. |
