Metabolite Identification

Common Name

2-Methoxy-1,3-benzenediol

Description

2-Methoxy-1,3-benzenediol, also known as 2-methoxyresorcinol or 2-O-methylpyrogallol, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. 2-Methoxy-1,3-benzenediol is an extremely weak basic (essentially neutral) compound (based on its pKa). BioTransformer predicts that 2-methoxy-1,3-benzenediol is a product of 1-(2,4-dihydroxy-3-methoxyphenyl)-2-(3-hydroxy-4-methoxyphenyl)propan-1-one metabolism via a keto-hydrolysis-pattern5 reaction occurring in human gut microbiota and catalyzed by an unspecified-gutmicro enzyme (PMID: 30612223 ).
