Description

tert-Dodecylthiol CAS NO 25103-58-6 is a branched-chain alkyl mercaptan widely used as a chain transfer agent and modifier in polymer synthesis. Its primary value lies in its ability to efficiently control polymer molecular weight and architecture, directly impacting the final material's properties. This product is essential for manufacturers in the polymer, rubber, and specialty chemical industries seeking to fine-tune product performance and process efficiency.

Application

• Primary chain transfer agent (CTA) in the production of styrene-butadiene rubber (SBR), acrylonitrile-butadiene rubber (NBR), and other synthetic rubbers.
• Molecular weight regulator in the free-radical polymerization of acrylics, methacrylates, and vinyl acetate.
• Key intermediate for the synthesis of specialty surfactants and lubricant additives.
• Modifier for polyolefin properties, influencing crystallinity and processability.
• Used in the manufacture of adhesives, sealants, and coatings to adjust viscosity and curing characteristics.
• Precursor for photoinitiators and other light-sensitive compounds.

Quality Control

Our tert-Dodecylthiol is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets precise specifications for use in sensitive polymerization processes. A Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents and bases.
