Abstract

The synthesis of 2,5‐dihydroxy[carboxy‐14C]benzoic acid (gentisic acid) is described. The procedure utilized [carboxy‐14C]salicylic acid as a starting material. Salicylic acid was converted to gentisic acid using potassium persulfate hydroxylation. The mixture of hydroxylation products in this reaction was easily separated by UV‐visualized quartz column chromatography to obtain the desired isomer in high purity (overall yield of 38%). This procedure may be used for micro and semimicro preparation of the title compound.
