Description

(2-Chloroethyl)Sulfamoyl Chloride is a versatile and highly reactive organosulfur compound that serves as a critical bifunctional building block in advanced organic synthesis. Its dual reactive sites make it invaluable for constructing complex molecular architectures, particularly in the development of active pharmaceutical ingredients (APIs) and agrochemicals. This intermediate is essential for research and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce sulfamoyl or chloroethyl functionalities.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of sulfonamide-based drugs, including diuretics, carbonic anhydrase inhibitors, and antiviral agents.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators that incorporate sulfamoyl moieties.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for producing specialty polymers with specific functional groups.
• Chemical Research: A valuable reagent in medicinal chemistry for structure-activity relationship (SAR) studies and library synthesis.
• Dye and Pigment Industry: Intermediate in the production of sulfonated dyes and colorants.
• Ligand and Catalyst Preparation: Used to synthesize novel ligands for metal complexes and catalysts.

Quality Control

Our (2-Chloroethyl)Sulfamoyl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay (by titration or HPLC), identity confirmation (IR, NMR), and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
