The world of thiols offers a variety of compounds, each with unique properties and applications. Among the most industrially relevant are Dodecyl Mercaptan variants, primarily Tertiary Dodecyl Mercaptan (TDM) and N-Dodecyl Mercaptan (NDM). While both are C12 thiols and share some overlapping uses, understanding their distinct characteristics is crucial for making informed purchasing decisions. As a comprehensive supplier of these essential chemicals, we aim to clarify these differences to help our B2B clients select the optimal product for their specific needs.

Tertiary Dodecyl Mercaptan (TDM) is characterized by its branched structure, stemming from oligomers of isobutylene trimer or propylene tetramer. This molecular architecture gives TDM specific reactivity profiles. It is particularly valued as a polymerization regulator, especially for styrene-butadiene rubber (SBR) and ABS resins, where it effectively controls molecular weight distribution and reduces chain branching. TDM is also employed as an intermediate in the synthesis of various chemicals, including fungicides, insecticides, and lubricating oil additives. Its 'gold water' application in the ceramic industry and its use as an oil well acidifier further highlight its versatility. When considering purchasing TDM, it's important to note its CAS number is typically 25103-58-6.

N-Dodecyl Mercaptan (NDM), on the other hand, features a linear chain structure (1-dodecanethiol). This linear configuration influences its reactivity and applications. NDM is widely used as a chain transfer agent in radical polymerization, notably for methyl methacrylate and styrene. It's also critical in the preparation of hydrophobic self-assembled monolayers (SAMs) due to its linear alkyl chain that facilitates ordered surface structures. NDM finds applications in lubricant intermediates, as a process regulator, and in the synthesis of antioxidants and metal nanoparticles. Its CAS number is commonly 112-55-0.

The choice between TDM and NDM often depends on the precise application requirements. For applications demanding specific branching control in polymers like SBR and ABS, TDM often proves superior. For linear polymer chains, self-assembled monolayers, or specific synthetic routes, NDM might be the preferred choice. Both are invaluable in their respective domains. As a supplier, we offer both TDM and NDM, ensuring you can access the exact chemical tailored to your industrial processes. Understanding these nuances allows us to provide you with the most effective solutions. When you need to buy high-purity dodecyl mercaptan, whether TDM or NDM, consider our expertise and reliable supply chain from China.
