Those are benzoic acids in which the hydrogen atom at position 4 of the benzene ring is replaced by a methoxy group. 3,4-dimethoxybenzoic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 3,4-dimethoxybenzoic acid can be synthesized from benzoic acid. 3,4-dimethoxybenzoic acid is also a parent compound for other transformation products, including but not limited to, 3beta-[(O-beta-D-glucopyranosyl-(1->4)-O-beta-D-glucopyranosyl-(1->6)-beta-D-glucopyranosyl)oxy]-17alpha-hydroxy-16beta-[(O-(2-O-3,4-dimethoxybenzoyl-beta-D-xylopyranosyl)-(1->3)-2-O-acetyl-alpha-L-arabinopyranosyl)oxy]cholest-5-en-22-one, 3beta-[(beta-D-glucopyranosyl)oxy]-17alpha-hydroxy-16beta-[(O-(2-O-3,4-dimethoxybenzoyl-beta-D-xylopyranosyl)-(1->3)-2-O-acetyl-alpha-L-arabinopyranosyl)oxy]cholest-5-en-22-one, and 3beta-[(O-beta-D-glucopyranosyl-(1->6)-beta-D-glucopyranosyl)oxy]-17alpha-hydroxy-16beta-[(O-(2-O-3,4-dimethoxybenzoyl-beta-D-xylopyranosyl)-(1->3)-2-O-acetyl-alpha-L-arabinopyranosyl)oxy]cholest-5-en-22-one. 3,4-dimethoxybenzoic acid can be found in coriander and olive, which makes 3,4-dimethoxybenzoic acid a potential biomarker for the consumption of these food products. 3,4-Dimethoxy-benzoic acid 3,4-Dimethylprotocatechuic acid Benzoic acid, 3,4-dimethoxy- Dimethylprotocatechuic acid Veratric acid Veratrumenoic acid Veratrylic acid C9H10O4 182.1733 182.057908808 3,4-dimethoxybenzoic acid veratric acid 93-07-2 COC1=C(OC)C=C(C=C1)C(O)=O InChI=1S/C9H10O4/c1-12-7-4-3-6(9(10)11)5-8(7)13-2/h3-5H,1-2H3,(H,10,11) DAUAQNGYDSHRET-UHFFFAOYSA-N belongs to the class of organic compounds known as p-methoxybenzoic acids and derivatives.
