Metabolite Identification
Common NamePyrazin-2-carboxylic acid
DescriptionPyrazin-2-carboxylic acid, also known as pyrazinoic acid or pyrazinoate, belongs to the class of organic compounds known as pyrazine carboxylic acids. These are heterocyclic compounds containing a pyrazine ring substituted by one or more carboxylic acid groups. Pyrazin-2-carboxylic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Pyrazin-2-carboxylic acid exists in all living organisms, ranging from bacteria to humans. These are heterocyclic compounds containing a pyrazine ring substituted by one or more carboxylic acid group.
