Description

5-Bromo-4-Chloro-2-Fluoro-Benzenesulfonylchloride is a high-value, multi-halogenated benzenesulfonyl chloride derivative, serving as a critical synthetic intermediate in advanced organic chemistry. Its core value lies in its reactive sulfonyl chloride group, which enables the efficient introduction of the corresponding sulfonamide or sulfonate moiety into complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing active ingredients and fine chemicals requiring specific halogen substitution patterns.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, especially in the development of kinase inhibitors, receptor antagonists, and other small-molecule therapeutics.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where the halogenated benzene core provides specific biological activity and stability.
• Material Science Precursor: Employed in the creation of specialty polymers, liquid crystals, and organic electronic materials that require sulfonated aromatic structures.
• Chemical Research & Development: A versatile reagent in academic and industrial R&D labs for exploring new synthetic pathways and creating compound libraries for screening.
• Dye and Pigment Manufacturing: Acts as an intermediate in the synthesis of specialized sulfonated dyes and colorants.

Quality Control

Our 5-Bromo-4-Chloro-2-Fluoro-Benzenesulfonylchloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets the high standards required for research and production. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 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 strong bases and oxidizing agents.
