Description

3-(4-Bromo-Phenyl)-Pyrrole-2,5-Dione is a high-purity brominated maleimide derivative, a versatile and critical building block in advanced organic synthesis. Its value lies in its reactive pyrrole-2,5-dione (maleimide) core, which readily undergoes Michael addition and Diels-Alder reactions, and the bromo-phenyl substituent that offers a handle for further cross-coupling transformations. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing novel active ingredients, as well as for material scientists creating specialized polymers and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of complex molecules for drug discovery and development, particularly for candidates targeting neurological disorders and cancers.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and plant growth regulators, leveraging its bioactive scaffold.
• Polymer & Material Science: Acts as a functional monomer or cross-linking agent in the production of high-performance polymers, resins, and smart materials with tailored thermal or mechanical properties.
• Organic Electronic Materials: Investigated as a building block for organic semiconductors, conductive polymers, and components in OLEDs or photovoltaic cells due to its electron-deficient structure.
• Bioconjugation & Probe Development: Utilized in bioconjugation chemistry to label proteins, peptides, or other biomolecules via its maleimide group's specificity for thiols.
• Chemical Research & Development: Employed as a standard or reagent in methodological studies for new organic reactions and catalytic processes.
