In-Stock Pyrazole Intermediates from Huateng Pharma for Research and Process Development

Huateng Pharma continues to expand its portfolio of heterocyclic building blocks with the availability of two pyrazole derivatives: 4-Methylpyrazole (CAS No. 7554-65-6) and 1-Methylpyrazole-4-carboxylic acid (CAS No. 5952-92-1). Both compounds are maintained in stock and available in bulk quantities to support ongoing research and scale-up requirements.

Technical Applications

4-Methylpyrazole (Fomepizole)
4-Methylpyrazole is a known inhibitor of alcohol dehydrogenase and is used in the treatment of methanol and ethylene glycol poisoning. In addition to its role in toxicology, it is also applied in biochemical studies and pharmaceutical research involving enzyme inhibition and metabolic pathways.

1-Methylpyrazole-4-carboxylic acid
This compound serves as a versatile heterocyclic intermediate in organic synthesis. It is used in the preparation of active pharmaceutical ingredients and has been reported in synthetic routes for small-molecule drug candidates, including those targeting cardiovascular conditions. Its structure makes it suitable for medicinal chemistry and process optimization work.
