Description

3-(4-Bromophenyl)-1-(4-Methoxyphenyl)-1H-Pyrazole-4-Carbaldehyde is a high-purity, functionalized pyrazole derivative serving as a critical advanced intermediate in organic synthesis. Its value lies in its bifunctional structure, featuring both a bromoaryl group and an aldehyde moiety, which enables versatile cross-coupling and condensation reactions. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing novel active ingredients, particularly for applications requiring complex heterocyclic scaffolds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of potential drug candidates, especially kinase inhibitors and other small molecule therapeutics.
• Agrochemical Research: Used in developing novel fungicides, herbicides, and insecticides that leverage the pyrazole core for bioactivity.
• Material Science: Serves as a precursor for functional organic materials, including ligands for metal-organic frameworks (MOFs) and organic semiconductors.
• Chemical Synthesis: The aldehyde group facilitates further derivatization (e.g., reductive amination, condensation) to create libraries of compounds for screening.
• Academic & R&D: A valuable reagent for methodological studies in organic chemistry, particularly in palladium-catalyzed cross-coupling reactions.
