Description

(4-Chlorosulfonyl-Phenyl)-Carbamic Acid Octyl Ester is a specialized organic intermediate featuring both a chlorosulfonyl and a carbamate functional group. This unique bifunctional structure makes it a valuable building block for the synthesis of more complex molecules, particularly in advanced material and pharmaceutical research. It is primarily sought by R&D chemists and process development scientists in the agrochemical, pharmaceutical, and specialty chemical industries for creating novel sulfonamide and urethane derivatives.

Application

• Pharmaceutical Intermediate: Key synthon for the development of novel drug candidates, especially those targeting enzyme inhibition via sulfonamide or carbamate moieties.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides where the chlorosulfonyl group enables further derivatization.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the development of specialty polymers, coatings, and resins with specific functional properties.
• Chemical Research & Development: A versatile building block for organic synthesis, facilitating the introduction of both sulfonyl chloride and carbamate functionalities in a single molecule.
• Dye & Pigment Industry: Potential intermediate in the synthesis of specialized colorants and photographic chemicals.

Quality Control

Our (4-Chlorosulfonyl-Phenyl)-Carbamic Acid Octyl Ester is manufactured under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) for long-term storage to prevent decomposition.
