Metabolite Identification
Common Name4-Hydroxymethylpyrazole
Description4-Hydroxymethylpyrazole belongs to the class of organic compounds known as pyrazoles. Pyrazoles are compounds containing a pyrazole ring, which is a five-member aromatic ring with two nitrogen atoms (at positions 1 and 2) and three carbon atoms. 4-Hydroxymethylpyrazole is a metabolite of fomepizole. 4-Hydroxymethylpyrazole is a moderately basic 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. Apart from medical uses, the role of 4-methylpyrazole in coordination chemistry has been studied.
