Description

2-Mercaptobutanedioic Acid Didodecyl Ester is a specialized organosulfur compound, also known by its CAS number 63979-81-7. This chemical serves as a high-performance intermediate and functional additive, valued for its unique combination of a thiol group and long alkyl chains. It is primarily sought by manufacturers in the polymer, lubricant, and specialty chemical industries for applications requiring metal chelation, antioxidant properties, or surface modification.

Application

• Polymer Stabilizer and Antioxidant: Acts as a multifunctional additive in plastics and synthetic rubbers to prevent thermal and oxidative degradation.
• Lubricant and Fuel Additive: Functions as an extreme pressure (EP) agent and anti-wear component in advanced lubricant formulations and fuel systems.
• Metal Chelating Agent: Used in metalworking fluids and industrial cleaning formulations to sequester heavy metal ions and prevent catalytic degradation.
• Surface Modifier and Coupling Agent: Imparts specific surface properties in coatings, adhesives, and composite materials due to its dual functional groups.
• Chemical Synthesis Intermediate: Serves as a key building block in the synthesis of more complex sulfur-containing specialty chemicals and pharmaceuticals.
• Corrosion Inhibitor: Provides protective properties in functional fluids and coatings for metal surfaces.
