Description

3-(Chlorosulfonyl)Propyl Acetate is a versatile sulfonyl chloride derivative and reactive chemical intermediate. This compound is valued for its bifunctional nature, featuring both a reactive chlorosulfonyl group and an ester moiety, enabling its use in the synthesis of more complex molecules. It is primarily sought by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing sulfonamide linkages and functionalized polymers.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those containing sulfonamide functional groups.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides where the sulfonyl group is integral to biological activity.
• Polymer Modification: Serves as a monomer or cross-linking agent for creating specialty polymers with specific surface properties or reactivity.
• Dye and Pigment Manufacturing: Intermediate in the synthesis of sulfonated dyes and colorants.
• Chemical Research & Development: A valuable reagent for organic synthesis and novel compound library development in R&D laboratories.
• Surface Active Agent Precursor: Used in the manufacture of specialized surfactants and detergents.

Quality Control

Our 3-(Chlorosulfonyl)Propyl Acetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis by GC/HPLC, to ensure it meets precise specifications for purity and reactivity. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept 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 and oxidizing agents.
