2-Hydroxy-3-methoxybenzoic acid was used as internal standard during the simultaneous quantification of acetylsalicylic acid and its metabolite salicylic acid in human plasma by high-performance liquid chromatography. It was used in large-scale synthesis of 7-methoxy-3(2H)-benzofuranone.
o-Vanillic Acid, is a derivative of Vanillic Acid (V097350), used as a flavoring agent. o-Vanillic Acid, is also a building block used for the synthesis of more complex pharmaceutical compounds such as Warfarin (W498500), and Phenprocoumon (P318820).
ChEBI: 3-methoxysalicylic acid is benzoic acid substituted with a hydroxy group at position C-2 and a methoxy group at position C-3. It has a role as a metabolite.
