Description

4-Bromo-3-Cyanobenyl Bromide is a versatile bifunctional aromatic intermediate of significant importance in advanced organic synthesis. Its dual reactive sites, the bromine and the cyano group, make it a critical building block for constructing complex molecular architectures. This compound is primarily needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries for creating novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules containing substituted benzyl or phenyl rings.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the bromine and nitrile functionalities allow for further derivatization.
• Ligand and Catalyst Development: Acts as a starting material for synthesizing specialized ligands used in transition metal catalysis and cross-coupling reactions.
• Material Science & Polymer Chemistry: Incorporated as a monomer or cross-linking agent in the production of high-performance polymers, liquid crystals, and organic electronic materials.
• Chemical Research & Development: Employed in academic and industrial R&D for exploring new synthetic pathways and creating compound libraries for screening.
• Dye and Pigment Intermediate: Utilized in the synthesis of specialized dyes and pigments where the cyano group modifies color properties and stability.

Quality Control

Our 4-Bromo-3-Cyanobenyl Bromide is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee compliance with your research and process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
