1-Dodecanethiol, also widely known in the industry as n-Dodecyl Mercaptan or NDM, is a high-performance organosulfur compound serving as the primary chain transfer agent in radical polymerization processes. This liquid chemical functions through its highly reactive thiol group to precisely regulate molecular weight and control the branching degree of polymer chains, ensuring optimal mechanical properties in the production of styrene-butadiene rubber and nitrile-butadiene rubber. In the industrial manufacture of specialized surfactants, lubricant additives, and photoinitiators, it acts as a critical intermediate for introducing hydrophobic alkyl chains and sulfur-containing functional groups into complex molecular architectures. We provide this material with competitive factory pricing, supporting requirements for customized specifications to meet the 98% high-purity standards required for sensitive elastomer synthesis. All shipments are accompanied by comprehensive MSDS, TDS, COA documentation to ensure full regulatory traceability and are available for bulk supply via specialized chemical logistics to support continuous large-scale industrial manufacturing.

FAQ - Technical & Supply Chain
-
Q:
How is the molecular weight control efficiency of 1-Dodecanethiol verified in synthetic rubber production?
A: The technical identity is confirmed via CAS 112-55-0, and its efficiency is typically measured by its chain transfer constant, which allows for consistent Mooney viscosity and processing stability in industrial-scale elastomer polymerization. -
Q:
Is the 98% grade of 1-Dodecanethiol suitable for use in the production of polymer additives?
A: Yes, this high-purity material is commonly applied as a reactive intermediate for synthesizing antioxidants and UV stabilizers, intended for professional industrial chemical formulation rather than general laboratory research.
