Description

3-Butenoic Acid, 4-(4-Bromophenyl)-2-Oxo-, Methyl Ester is a specialized brominated α,β-unsaturated ester, a high-purity intermediate of significant interest in advanced organic synthesis. Its core value lies in its unique molecular scaffold, which combines a reactive α,β-unsaturated carbonyl system with a bromophenyl moiety, making it a versatile building block for constructing complex molecules. This compound is primarily needed by research and development chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and inflammatory pathways.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators, leveraging the bioactivity of the bromophenyl group.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers with tailored optical or electronic properties.
• Ligand and Catalyst Development: Employed in the preparation of complex organic ligands for asymmetric catalysis and metal-organic frameworks (MOFs).
• Chemical Biology Probes: Utilized as a building block for creating molecular probes to study enzyme function and biological pathways.
• Academic & Industrial R&D: A valuable reagent for methodological studies in organic chemistry, including cross-coupling reactions and cycloadditions.
