Description

3-Chloro-4-(3-Pyridin-3-Yl-Ureido)-Benzenesulfonyl Chloride Hydrogen Sulfate is a high-purity, advanced pharmaceutical intermediate characterized by its sulfonyl chloride and urea functional groups. This compound is of significant commercial importance for its role as a key building block in the synthesis of complex active pharmaceutical ingredients (APIs). It is primarily required by research institutions and manufacturers in the pharmaceutical and agrochemical industries for developing novel therapeutic and crop protection agents.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of sulfonamide-based drug candidates, particularly for targeted therapies.
• API Development: Used in research and development for creating new active pharmaceutical ingredients with specific receptor-binding properties.
• Agrochemical Synthesis: Serves as a building block for developing advanced herbicides and fungicides that require sulfonylurea or sulfonamide moieties.
• Chemical Research: Employed in academic and industrial R&D for studying structure-activity relationships (SAR) and novel organic reactions.
• Custom Synthesis: Utilized by contract research and manufacturing organizations (CROs/CMOs) for client-specific molecule production.

Quality Control

Our 3-Chloro-4-(3-Pyridin-3-Yl-Ureido)-Benzenesulfonyl Chloride Hydrogen Sulfate 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 intermediate 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 anhydrous conditions to prevent degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
