Description

2-Octanethiol is a versatile aliphatic thiol compound, primarily valued for its role as a chain transfer agent in polymer synthesis and as a key intermediate in the production of specialty chemicals. Its ability to modify polymer molecular weight and structure makes it essential for achieving specific material properties in industrial applications. This product is critical for manufacturers in the polymer, lubricant additive, and agrochemical sectors seeking precise control over their synthesis processes.

Application

• Polymer Industry: Acts as a highly effective chain transfer agent (CTA) in free-radical polymerization processes, such as for styrene, acrylates, and vinyl acetate, to control molecular weight and polydispersity.
• Lubricant & Fuel Additives: Serves as a precursor for the synthesis of extreme pressure (EP) additives, anti-wear agents, and corrosion inhibitors used in advanced lubricant formulations.
• Agrochemical Synthesis: Utilized as a key intermediate in the manufacture of certain pesticides, herbicides, and fungicides, contributing to the sulfur-containing active ingredients.
• Flavor & Fragrance Industry: Employed in the synthesis of sulfur-containing aroma compounds, contributing to savory or meaty notes in complex flavor profiles.
• Chemical Intermediate: Used in organic synthesis for introducing the octylthio group, and in the production of surfactants, plasticizers, and other specialty chemicals.
• Rubber & Elastomer Production: Functions as a peptizing agent or modifier in the processing of synthetic rubbers to improve plasticity and processing characteristics.

Quality Control

Our 2-Octanethiol is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical processes.

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 nature as a thiol, it is recommended to store under an inert atmosphere (e.g., nitrogen) to minimize oxidation. Recommended storage temperature: 2-25°C.
