Description

4-Dodecylbenzenesulfonyl Chloride is a key organic intermediate characterized by its long alkyl chain and reactive sulfonyl chloride group. This compound matters for its role as a versatile building block in the synthesis of surfactants, specialty chemicals, and pharmaceutical agents. It is primarily needed by manufacturers in the agrochemical, polymer, and fine chemical industries for producing sulfonamides, detergents, and functional materials.

Application

• Surfactant and Detergent Synthesis: Serves as a crucial precursor for the production of anionic surfactants like linear alkylbenzene sulfonates (LAS).
• Agrochemical Intermediates: Used in the manufacture of sulfonamide-based herbicides, fungicides, and plant growth regulators.
• Polymer Additives: Acts as a modifier or chain-transfer agent in polymerization processes to alter polymer properties.
• Pharmaceutical Building Block: Employed in the synthesis of various sulfonamide drugs and active pharmaceutical ingredients (APIs).
• Dye and Pigment Manufacturing: Functions as an intermediate in the production of sulfonated dyes and colorants.
• Lubricant and Fuel Additives: Utilized to create sulfonate additives that improve detergency and corrosion inhibition.
• Research & Development: A valuable reagent in organic chemistry research for introducing the dodecylbenzenesulfonyl moiety.
• Ion-Exchange Resins: Can be used in the preparation of specialized resins for separation and purification processes.

Quality Control

Our 4-Dodecylbenzenesulfonyl Chloride undergoes rigorous quality testing to ensure compliance with industry standards. Production follows strict in-process controls, and each batch is analyzed to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay, color, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept sealed under dry conditions to prevent hydrolysis. Keep away from strong bases, oxidizers, and sources of heat.
