Description

2,3,3,4,4,5-Hexamethylhexane-2-Thiol CAS NO 90501-34-1 is a high-purity, branched-chain tertiary thiol compound characterized by its unique sterically hindered structure. This molecular architecture is critical for its role as a highly effective chain transfer agent and modifier in radical polymerization processes, enabling precise control over polymer molecular weight and architecture. It is an essential specialty chemical for R&D and production in advanced polymer synthesis, particularly for manufacturers of high-performance elastomers, adhesives, and specialty resins requiring tailored properties.

Application

• Chain Transfer Agent (CTA) in Radical Polymerization: Used to control molecular weight and polydispersity in the production of acrylics, styrenics, and other vinyl polymers.
• Modifier for Polymer Architecture: Enables the synthesis of telechelic polymers and macromonomers due to its reactive thiol group.
• Synthesis of High-Performance Elastomers: A key intermediate in creating specialty rubbers with enhanced thermal stability and mechanical properties.
• Surface Modification Agent: Imparts specific surface characteristics to polymers and coatings.
• Lubricant and Fuel Additive Intermediate: Serves as a precursor for synthesizing extreme pressure (EP) additives and antioxidants.
• Pharmaceutical & Agrochemical Intermediates: Used in the synthesis of complex molecules where a sterically hindered thiol functionality is required.
• Crosslinking Agent for Specialty Resins: Facilitates the formation of networks in thermosetting polymers.
• Research & Development: A valuable building block in organic synthesis and materials science research.
