Description

Methyl 2-{[4-(Chlorosulfonyl)Butyl]Amino}Benzoate is a specialized organic synthesis intermediate featuring both a reactive chlorosulfonyl group and a protected amino benzoate moiety. This compound matters for its role as a key building block in the development of advanced pharmaceutical agents and functional materials, enabling precise molecular modifications. It is primarily needed by research and development chemists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing complex molecules with specific sulfonamide linkages.

Application

• As a critical pharmaceutical intermediate in the synthesis of novel drug candidates, particularly those targeting enzyme inhibition.
• In the research and development of agrochemicals, such as herbicides and fungicides, requiring sulfonamide-based active ingredients.
• For the preparation of functional dyes and pigments, where the sulfonyl chloride group allows for covalent bonding to polymers or other substrates.
• As a building block in polymer chemistry for creating specialty monomers with pendant reactive groups.
• In material science research for surface modification and the development of advanced coatings.
• For the synthesis of bioconjugates and probes used in biochemical and diagnostic applications.

Quality Control

Our Methyl 2-{[4-(Chlorosulfonyl)Butyl]Amino}Benzoate is produced under a strict quality management system. 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 process development. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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.
