Metabolite Identification
Common Name2-Pyrocatechuic acid
Description2-Pyrocatechuic acid, also known as 2,3-dihydroxybenzoate or O-pyrocatechuate, belongs to the class of organic compounds known as salicylic acids. These are ortho-hydroxylated benzoic acids. 2-Pyrocatechuic acid is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Pyrocatechuic acid exists in all living organisms, ranging from bacteria to humans.
