Metabolite Identification
Common NameO-Phenolsulfonic acid
Description2-hydroxybenzenesulfonic acid, also known as O-phenolsulfonic acid or O-phenolsulphonate, belongs to the class of organic compounds known as benzenesulfonic acids and derivatives. These are organic compounds containing a sulfonic acid or a derivative thereof that is linked to a benzene ring. An arenesulfonic acid that is phenol substituted by a sulfo group at C-2. 2-hydroxybenzenesulfonic acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
