Description

1-Dodecanesulfonyl Chloride is a versatile long-chain sulfonyl chloride derivative, serving as a critical building block in organic synthesis. Its primary value lies in its ability to act as an effective sulfonylation agent, introducing the dodecylsulfonyl functional group to create surfactants, specialty polymers, and biologically active molecules. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and material science industries seeking to modify solubility, stability, or surface activity.

Application

• Pharmaceutical Intermediates: Key reagent in the synthesis of sulfonamide drugs and other active pharmaceutical ingredients (APIs).
• Surfactant & Detergent Synthesis: Used to produce anionic surfactants with long hydrophobic tails for industrial and household cleaning formulations.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to impart specific properties to specialty polymers and resins.
• Agrochemical Production: Intermediate in the manufacture of herbicides, fungicides, and plant growth regulators.
• Lubricant Additives: Employed in creating extreme pressure (EP) additives and anti-wear agents for advanced lubricants.
• Research & Development: A valuable tool in organic chemistry labs for probing reaction mechanisms and developing new synthetic methodologies.
• Dye & Pigment Industry: Used in the synthesis of sulfonated dyes to enhance water solubility and fiber affinity.

Quality Control

Our 1-Dodecanesulfonyl Chloride is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including assay by titration and impurity profiling, to ensure it meets the high-purity standards required for sensitive synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to prevent decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
