Description

4-(Chlorosulfonyl)Benzamide is a high-purity, reactive organic intermediate featuring both a chlorosulfonyl and a benzamide functional group. This compound is valued for its role as a versatile building block in the synthesis of more complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists in the fine chemical and active pharmaceutical ingredient (API) manufacturing sectors.

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 that utilize the sulfonamide moiety for biological activity.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers and functional materials.
• Chemical Biology Probes: Employed in the design and synthesis of molecular probes for studying biological pathways and protein interactions.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis projects requiring the introduction of a reactive sulfonyl chloride group onto an aromatic amide scaffold.

Quality Control

Our 4-(Chlorosulfonyl)Benzamide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for research and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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.
