Metabolite Identification
Common Name4-Carboxypyrazole
Description4-Carboxypyrazole belongs to the class of organic compounds known as pyrazole carboxylic acids and derivatives. These are heterocyclic compounds containing a pyrazole ring in which a hydrogen atom is replaced by a carboxylic acid group. 4-Carboxypyrazole is an extremely weak basic (essentially neutral) compound (based on its pKa). It may be used alone or in combination with hemodialysis. Fomepizole or 4-methylpyrazole is indicated for use as an antidote in confirmed or suspected methanol or ethylene glycol poisoning. 4-Carboxypyrazole is a metabolite of fomepizole. Apart from medical uses, the role of 4-methylpyrazole in coordination chemistry has been studied.
