Description

4-Bromo-2,5-Dimethylbenzenesulfonyl Chloride (Saltdata: Free) is a high-purity, versatile sulfonyl chloride derivative, a crucial building block in advanced organic synthesis. Its primary value lies in its reactivity as a sulfonylation agent, enabling the introduction of the sulfonyl functional group to create novel compounds with specific properties. This intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, particularly for developing active pharmaceutical ingredients (APIs), crop protection agents, and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in the development of next-generation herbicides, fungicides, and pesticides with enhanced efficacy and selectivity.
• Material Science: Serves as a monomer or cross-linking agent for creating specialty polymers, resins, and functional surfaces.
• Dye and Pigment Manufacturing: Employed in the synthesis of complex organic dyes and pigments, particularly sulfonated azo dyes.
• Chemical Research & Development: A valuable reagent for medicinal chemistry, process chemistry, and exploring new synthetic pathways in academic and industrial R&D labs.
• Ligand and Catalyst Design: Used to synthesize specialized ligands for catalysis and metal-organic frameworks (MOFs).

Quality Control

Our 4-Bromo-2,5-Dimethylbenzenesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee traceability and compliance with your research or production requirements.

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 hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from moisture. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
