Description

1-Dodecanethiol is a high-purity, long-chain alkyl mercaptan widely used as a versatile chemical intermediate and chain transfer agent. Its primary value lies in its ability to control polymer molecular weight and modify surface properties in various industrial processes. This product is essential for manufacturers in the polymer, rubber, and specialty chemical industries seeking reliable quality and consistent performance.

Application

• Polymerization Modifier: Acts as a highly effective chain transfer agent (CTA) in the production of synthetic rubbers like styrene-butadiene rubber (SBR) and acrylonitrile-butadiene rubber (NBR) to control molecular weight and polymer structure.
• Surface Modification Agent: Used to functionalize nanoparticles, gold surfaces, and other materials to impart specific chemical properties or improve dispersion.
• Lubricant & Fuel Additive: Serves as an intermediate in the synthesis of extreme pressure (EP) additives for lubricating oils and as a precursor for fuel detergents.
• Chemical Synthesis Intermediate: A key building block for producing other organosulfur compounds, surfactants, and pharmaceutical intermediates.
• Rubber Processing Aid: Functions as a peptizing agent to reduce the viscosity of natural and synthetic rubber during mastication, improving processability.
• Flotation Agent: Employed in mineral processing as a collector for sulfide ores.

Quality Control

Our 1-Dodecanethiol is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) to verify identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 15-25°C.
