Description

4,4-Bis(Dodecylthio)Pentanoic Acid is a specialized organosulfur compound featuring a pentanoic acid backbone with two long-chain dodecylthio substituents. This unique structure makes it a valuable intermediate and functional additive, particularly as a stabilizer or chain transfer agent in polymer synthesis and modification. It is primarily sought by manufacturers in the polymer, lubricant, and specialty chemical industries for applications requiring precise molecular control and enhanced material properties.

Application

• Polymer Additive: Acts as a chain transfer agent or stabilizer in the production of polymers like polyolefins and acrylics to control molecular weight and improve processability.
• Lubricant & Grease Formulation: Serves as an extreme pressure (EP) additive or anti-wear agent in industrial lubricants and metalworking fluids.
• Specialty Chemical Intermediate: Used in the synthesis of more complex surfactants, corrosion inhibitors, and other functional chemicals.
• Rubber & Elastomer Processing: Functions as a peptizing agent or vulcanization modifier to enhance the properties of synthetic rubbers.
• Fuel & Oil Additive: Employed as a detergent or dispersant additive in fuel and engine oil formulations to prevent deposit formation.
• Research & Development: Utilized in academic and industrial R&D for studying sulfur-containing compounds and developing new materials.

Quality Control

Our 4,4-Bis(Dodecylthio)Pentanoic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by HPLC and identification by FT-IR, to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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). This material is easily oxidized and should be handled under an inert atmosphere (e.g., nitrogen) for long-term storage or when opening containers to prevent degradation. Keep away from strong oxidizing agents.
