Description

2',4'-Dimethoxy-Biphenyl-3-Sulfonyl Chloride is a high-purity sulfonyl chloride derivative, a critical building block in advanced organic synthesis. Its value lies in its reactive sulfonyl chloride group, which enables efficient introduction of the sulfonyl moiety into complex molecular architectures. This intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing active pharmaceutical ingredients (APIs) and novel crop protection agents.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in the development of novel herbicides and fungicides where the biphenyl-sulfonyl structure imparts specific biological activity.
• Material Science Research: Serves as a monomer or cross-linking agent in the creation of specialized polymers with tailored properties.
• Chemical Biology Probes: Employed in the design and synthesis of activity-based probes for studying enzyme function and protein labeling.
• Custom Synthesis & Contract Manufacturing: A vital starting material for fine chemical companies offering bespoke synthesis services for clients in life sciences.

Quality Control

Every batch of 2',4'-Dimethoxy-Biphenyl-3-Sulfonyl Chloride is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your research or production standards.

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). This compound is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as strong bases, amines, and alcohols.
