Salicylic acids are ortho-hydroxylated benzoic acids. 2,6-dihydroxybenzoic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). 2,6-dihydroxybenzoic acid can be found in beer and olive, which makes 2,6-dihydroxybenzoic acid a potential biomarker for the consumption of these food products. 2,6-dihydroxybenzoic acid can be found primarily in blood and urine. 2,6-Dihydroxybenzoic acid (γ-resorcylic acid) is a dihydroxybenzoic acid. It is a very strong acid due to its intramolecular hydrogen bonding . g-Resorcylic acid, 8CI Resorcinol-2-carboxylic acid C7H6O4 154.121 154.026608673 2,6-dihydroxybenzoic acid 2,6-dihydroxybenzoic acid 303-07-1 OC(=O)C1=C(O)C=CC=C1O InChI=1S/C7H6O4/c8-4-2-1-3-5(9)6(4)7(10)11/h1-3,8-9H,(H,10,11) AKEUNCKRJATALU-UHFFFAOYSA-N belongs to the class of organic compounds known as salicylic acids.
