Description

3,5-Dibromonitro Benzene CAS NO 6311-60-0 is a halogenated nitroaromatic compound that serves as a versatile and critical synthetic intermediate in advanced organic chemistry. Its value lies in the strategic positioning of bromine and nitro groups on the benzene ring, enabling selective functionalization for constructing complex molecular architectures. This high-purity intermediate is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to develop active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring brominated aromatic cores.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides, where the nitro and bromo groups facilitate further coupling reactions.
• Organic Synthesis Reagent: Employed in cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig) and nucleophilic aromatic substitution to create complex organic molecules.
• Dye and Pigment Manufacturing: Acts as a precursor for synthesizing brominated azo dyes and other colored compounds.
• Material Science Research: Serves as a monomer or functionalization agent in the development of specialty polymers and advanced organic materials.
• Chemical Research & Development: A valuable standard and starting material in academic and industrial R&D labs for methodological studies and novel compound discovery.
