Description

4'-Bromo-2-Nitro-Biphenyl is a specialized brominated nitroaromatic compound that serves as a crucial synthetic intermediate in advanced organic chemistry. Its value lies in its unique molecular structure, which provides reactive sites for constructing complex molecules, particularly in the synthesis of pharmaceuticals and functional materials. This product is essential for R&D chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries who require high-purity building blocks for their synthetic pathways.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those with biphenyl or halogenated aromatic scaffolds.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and pesticides, leveraging its halogen and nitro functional groups.
• Material Science Research: Acts as a building block for creating organic electronic materials, such as charge-transport molecules or ligands for metal-organic frameworks (MOFs).
• Ligand and Catalyst Development: Serves as a starting material for synthesizing specialized ligands used in catalytic systems for cross-coupling and other organic transformations.
• Dye and Pigment Intermediate: Utilized in the development of specialized colorants and pigments due to its nitro-aromatic structure.
• Academic and Industrial R&D: A valuable reagent for methodological studies in organic synthesis, including Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions.

Quality Control

Our 4'-Bromo-2-Nitro-Biphenyl is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, impurities, and physical characteristics are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and incompatible materials.
