Description

tert-Hexadecyl Mercaptan CAS NO 25360-09-2 is a high-purity, branched-chain alkyl mercaptan (thiol) characterized by its tertiary carbon structure bonded to the sulfhydryl group. This specific molecular architecture is critical for its role as a highly effective chain transfer agent and modifier in free-radical polymerization processes. It is an essential raw material for manufacturers in the polymer and specialty chemical industries seeking to control molecular weight and tailor polymer properties. Key applications include the production of synthetic rubbers, lubricant additives, and surface-active agents.

Application

• Polymerization Chain Transfer Agent: Primarily used to regulate molecular weight and polydispersity in the synthesis of styrene-butadiene rubber (SBR), acrylonitrile-butadiene-styrene (ABS), and other specialty polymers.
• Lubricant and Fuel Additive Intermediate: Serves as a key precursor in manufacturing extreme pressure (EP) additives, anti-wear agents, and detergents for advanced lubricating oils and industrial fuels.
• Surface Modifier and Coupling Agent: Utilized to functionalize surfaces of fillers, pigments, and nanoparticles to improve dispersion and compatibility within polymer matrices.
• Pharmaceutical and Agrochemical Synthesis: Acts as a building block or intermediate in the synthesis of complex molecules for pharmaceutical active ingredients and crop protection agents.
• Gold Recovery and Metal Chelation: Employed in hydrometallurgical processes for the selective extraction and recovery of precious metals like gold due to its strong affinity for metal ions.
• Odorant and Warning Agent: Used in trace amounts to impart a distinctive odor to naturally odorless gases (e.g., propane, natural gas) for leak detection and safety.

Quality Control

Our tert-Hexadecyl Mercaptan is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and assay, to ensure it meets precise specifications for critical parameters such as mercaptan content and branching ratio. Certificates of Analysis (COA) documenting all test results are provided and available upon request, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area under an inert atmosphere (e.g., nitrogen) to prevent oxidation. Recommended storage temperature is 2-8°C (36-46°F) for extended shelf life. Keep away from heat, sparks, open flames, and strong oxidizing agents.
