4-Hydroxymethylpyrazole (Standard)

4-Hydroxymethylpyrazole (Standard) is an analytical standard for 4-Hydroxymethylpyrazole (HY-33914) . This product is intended for research and analytical applications. 4-Hydroxymethylpyrazole is the primary metabolite of fomepizole (HY-B0876) via hepatic oxidative metabolism. 4-Hydroxymethylpyrazole exhibits a plasma concentration that is positively correlated with the administered dosage of Fomepizole, and it demonstrates a relatively short half-life. 4-Hydroxymethylpyrazole inhibits alcohol dehydrogenase (ADH) in humans and monkeys, but the inhibition constant is much higher than that of fomepizole and is therefore negligible in vivo[1]
