Description

5-Bromo-2-Chloro-Benzoyl Chloride is a high-purity aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its dual halogen functionality, which enables selective and efficient derivatization for creating complex molecular architectures. This intermediate is essential for research and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring halogenated benzoyl motifs.
• Agrochemical Synthesis: Used in the manufacturing of herbicides, fungicides, and insecticides where the bromo and chloro substituents influence bioactivity.
• Ligand and Catalyst Development: Serves as a starting material for creating specialized ligands used in metal-catalyzed cross-coupling reactions.
• Polymer Chemistry: Employed in the production of specialty polymers and liquid crystals, where it acts as a monomer or modifying agent.
• Dyestuff and Pigment Manufacturing: Intermediate for synthesizing complex halogenated dyes and organic pigments.
• Custom Synthesis and R&D: A versatile reagent for contract research organizations and academic laboratories exploring new chemical entities.

Quality Control

Our 5-Bromo-2-Chloro-Benzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles 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 room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and water.
