Description

tert-Decanethiol CAS NO 30174-58-4 is a branched-chain alkyl thiol, specifically a tertiary decanethiol, valued for its role as a versatile chain transfer agent and intermediate in organic synthesis. Its molecular structure makes it a highly effective modifier for controlling polymer molecular weight and architecture in radical polymerization processes. This compound is essential for manufacturers in the polymer, specialty chemical, and lubricant additive industries seeking to fine-tune material properties.

Application

• Polymer Industry: Primary use as a highly efficient chain transfer agent (CTA) in the production of acrylics, styrenics, and other vinyl polymers to regulate molecular weight and polydispersity.
• Specialty Chemical Synthesis: Key intermediate for introducing the tert-decylthio group into molecules for applications in surfactants, lubricant additives, and corrosion inhibitors.
• Lubricant & Fuel Additives: Used in the synthesis of sulfur-containing additives that provide extreme pressure (EP) and anti-wear properties.
• Surface Modification: Employed to create self-assembled monolayers (SAMs) on metal surfaces for corrosion protection or to alter surface energy.
• Pharmaceutical & Agrochemical Intermediates: Serves as a building block for synthesizing more complex sulfur-containing active ingredients.
• Rubber & Elastomer Production: Acts as a molecular weight regulator and cross-linking agent modifier in synthetic rubber manufacturing.

Quality Control

Our tert-Decanethiol 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 exacting specifications for use in sensitive polymerization and synthesis applications. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents and bases. Recommended storage temperature: 2-25°C.
