Description

1-Octadecanesulfonyl Chloride is a high-purity, long-chain sulfonyl chloride derivative, serving as a critical intermediate in advanced organic synthesis. Its primary value lies in its role as a versatile building block for introducing the octadecylsulfonyl moiety, enabling the creation of surfactants, phase-transfer catalysts, and specialized polymers. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and specialty materials industries seeking to modify surface properties or create novel functional molecules.

Application

• Surfactant & Detergent Intermediate: Key precursor for synthesizing anionic surfactants with long hydrophobic chains for industrial and household cleaning formulations.
• Pharmaceutical Synthesis: Used as a sulfonating agent in the production of active pharmaceutical ingredients (APIs) and prodrugs.
• Agrochemical Manufacturing: Intermediate in creating herbicides, fungicides, and plant growth regulators with enhanced bioavailability.
• Polymer Modification: Employed to introduce sulfonyl groups into polymers for improved solubility, adhesion, or ion-exchange properties.
• Lubricant & Fuel Additive Precursor: Basis for synthesizing extreme-pressure additives and corrosion inhibitors.
• Research & Development: Valuable reagent in academic and industrial R&D for exploring new organic reactions and material science applications.
• Dye & Pigment Industry: Used in the synthesis of sulfonated dyes and colorants for textiles and plastics.

Quality Control

Our 1-Octadecanesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and identification by FT-IR, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
