Description

(Undecylthio)-Acetic Acid is a specialized organosulfur compound featuring a long alkyl chain terminated with a thioacetic acid functional group. This unique structure makes it a valuable intermediate for synthesizing surfactants, lubricant additives, and specialty polymers. It is primarily sought after by R&D chemists and production engineers in the fine chemical, agrochemical, and advanced materials sectors for its role in introducing hydrophobic, sulfur-containing moieties.

Application

• Surfactant & Detergent Intermediate: Serves as a key building block for synthesizing anionic surfactants with enhanced oil solubility and wetting properties.
• Lubricant & Fuel Additive Precursor: Used to create extreme pressure (EP) additives and anti-wear agents for industrial lubricants and functional fluids.
• Polymer Modification Agent: Employed to introduce long-chain thioether groups into polymers, modifying their flexibility, hydrophobicity, and chemical resistance.
• Agrochemical Synthesis: Acts as an intermediate in the production of certain herbicides and fungicides that require specific lipid-soluble characteristics.
• Pharmaceutical Intermediate: Utilized in research for the synthesis of drug candidates where a lipophilic, sulfur-based linker is needed.
• Corrosion Inhibitor Formulation: Incorporated into formulations designed to protect metal surfaces in harsh environments.

Quality Control

Our (Undecylthio)-Acetic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, strong bases, and strong oxidizing agents. Due to its organic solvent and acidic nature, ensure containers are kept upright and sealed when not in use to prevent contamination and moisture uptake.
