Description

Nonyl Mercaptoacetate is a versatile organosulfur compound primarily used as a chain transfer agent and intermediate in polymer synthesis. Its unique structure, featuring a long alkyl chain and a reactive thioester group, makes it a critical component for controlling molecular weight and modifying polymer properties. This chemical is essential for manufacturers in the polymer, plastics, and specialty chemical industries seeking to fine-tune product characteristics such as viscosity, flexibility, and processability.

Application

• Chain Transfer Agent (CTA) in Polymerization: Used in free-radical polymerization processes, particularly for acrylics, vinyl acetate, and styrenics, to regulate polymer molecular weight and prevent gelation.
• Polymer Modification Intermediate: Serves as a key intermediate for introducing functional thiol groups into polymer backbones, enabling further cross-linking or property enhancement.
• Production of Specialty Surfactants and Lubricant Additives: Acts as a building block for synthesizing sulfur-containing surfactants and extreme pressure (EP) additives for industrial lubricants.
• Synthesis of Organic Sulfur Compounds: Utilized in organic synthesis as a precursor for various mercaptans, thioesters, and other sulfur-based fine chemicals.
• Adhesive and Sealant Formulations: Incorporated into formulations to modify cure profiles and improve the adhesion properties of acrylic- and urethane-based systems.
• Cross-linking Agent for Rubber and Elastomers: Facilitates vulcanization and cross-linking in the production of certain synthetic rubbers, enhancing thermal and mechanical stability.

Quality Control

Our Nonyl Mercaptoacetate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications for industrial applications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents, strong bases, and strong acids. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and prevent degradation.
