Description

4-Bromo-5-Ethyl-1-Methyl-1H-Pyrazole-3-Carboxylic Acid (Wxc08266) is a high-purity pyrazole derivative serving as a critical building block in advanced organic synthesis. This compound matters for its role as a versatile intermediate in the development of novel active pharmaceutical ingredients (APIs) and agrochemicals. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce specific brominated pyrazole motifs into their target molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and inflammatory diseases.
• Agrochemical Synthesis: Used in the research and development of next-generation herbicides and fungicides, leveraging the bioactivity of the pyrazole core.
• Ligand and Catalyst Development: Serves as a functionalized ligand for metal complexes in catalytic applications and materials science.
• Chemical Biology Probes: Employed in the creation of molecular probes for studying enzyme function and biological pathways.
• Advanced Material Research: Building block for functional polymers and organic electronic materials due to its conjugated structure.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for client-specific synthetic routes.
