Description

2-Ethoxy-5-(3-Ethyl-Ureido)-Benzenesulfonyl Chloride is a specialized sulfonyl chloride derivative, a key chemical intermediate prized for its reactive sulfonyl chloride group and functionalized aromatic ring. This compound is critical for the synthesis of more complex molecules, particularly in the development of active pharmaceutical ingredients (APIs) and advanced agrochemicals. It is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors for constructing sulfonamide-based structures.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of novel sulfonamide-based drug candidates, including potential enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and pesticides where the sulfonamide moiety imparts specific biological activity.
• Fine Chemical Production: Serves as a versatile intermediate for creating specialty chemicals, dyes, and functional materials requiring a sulfonyl chloride handle.
• Biochemical Research: Employed in proteomics and chemical biology for modifying peptides, proteins, or other biomolecules via sulfonylation reactions.
• Polymer Chemistry: Can be utilized to introduce sulfonamide functional groups into polymer chains to alter material properties like solubility or reactivity.

Quality Control

Our 2-Ethoxy-5-(3-Ethyl-Ureido)-Benzenesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical and fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical processes.

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). 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 heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
