Description

Dodecanethiol CAS NO 1322-36-7 is a versatile, long-chain alkyl thiol primarily used as a chain transfer agent and modifier in polymer chemistry. Its ability to control molecular weight and introduce specific functional groups makes it a critical component for achieving desired material properties in advanced syntheses. This high-purity chemical is essential for R&D and production in the polymer, rubber, and specialty chemical industries, where precise control over polymerization processes is paramount.

Application

• Chain Transfer Agent (CTA) in Polymerization: Crucial for controlling molecular weight and polydispersity in the production of styrene-butadiene rubber (SBR), acrylonitrile-butadiene-styrene (ABS), and other synthetic rubbers and plastics.
• Surface Modifier for Nanoparticles: Used to functionalize gold, silver, and quantum dot surfaces to improve dispersion, stability, and compatibility in composite materials and inks.
• Lubricant and Fuel Additive Intermediate: Serves as a precursor in the synthesis of extreme pressure (EP) additives, anti-wear agents, and corrosion inhibitors for industrial lubricants and specialty fuels.
• Pharmaceutical and Agrochemical Intermediate: Acts as a building block for synthesizing more complex sulfur-containing compounds used in active pharmaceutical ingredients (APIs) and crop protection agents.
• Flotation Agent in Mining: Employed as a collector in the froth flotation process for the separation and concentration of sulfide ores.
• Adhesion Promoter: Enhances the bonding interface in rubber-to-metal bonding applications and certain adhesive formulations.

Quality Control

Our Dodecanethiol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC and titration to verify key parameters such as assay and thiol content. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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.
