biological activity: 3, 5-dihydroxybenzoicacid (α-resorcylicacid) is a primary metabolite of alkylresinols. Alkylresinols can be hydrolyzed by liver enzymes in phase I metabolism.

Target :HumanEndogenousMetabolite

chemical properties of white or light pink needle crystal. Melting point 232-233℃. Soluble in ethanol, ether, acetone and hot water. Reaction with fuming sulfuric acid or hot concentrated sulfuric acid to produce Chemicalbook purplish red compound. Reacts with ferric chloride to produce wine color.

Use as organic synthesis intermediate, used in pharmaceutical, synthetic resin and other uses for organic synthesis

production method from benzoic acid by sulfonation, alkali melting, acidification. Benzoic acid was sulfonated with fumigant sulfuric acid at 240-250℃ for 5h to produce 3, 5-disulfonic benzoic acid, and then alkaline melted with sodium hydroxide at 300℃. The reaction product obtained was neutralized by sulfuric acid to weak basic, filtered and concentrated, acidified to weak acidic, and extracted with ether. The crude product obtained from diethyl ether recovery from the extract was recrystalized with water to obtain the finished product.
