Description

4-(Diethylcarbamoyl)Benzene-1-Sulfonyl Chloride is a specialized sulfonyl chloride derivative, a key reactive intermediate in advanced organic synthesis. This compound matters for its role as a versatile building block, enabling the introduction of the sulfonamide pharmacophore into target molecules. It is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the development of new active ingredients.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of novel sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and pesticides that utilize sulfonamide chemistry for enhanced efficacy.
• Chemical Biology & Proteomics: Serves as a reactive handle for labeling or modifying biomolecules in probe development and activity-based protein profiling (ABPP) studies.
• Material Science Research: Employed in the creation of functional polymers and advanced materials where the sulfonyl chloride group facilitates covalent attachment to other components.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for the production of bespoke compounds and small-scale API (Active Pharmaceutical Ingredient) batches.

Quality Control

Our 4-(Diethylcarbamoyl)Benzene-1-Sulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing all specifications 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 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 strong bases and oxidizing agents.
