Dodecyl mercaptan

Dodecyl Mercaptan (CAS 112-55-0), also known as NDM, 1-Dodecanethiol, or Mercaptan C12, is a long-chain aliphatic thiol with the molecular formula C12H26S. It carries no assigned E-code and is classified under HS code 29309070. It is registered under REACH and listed in EC inventory under number 203-984-1.

In polymer manufacturing, Dodecyl Mercaptan acts as a chain-transfer agent during free-radical polymerization, controlling molecular weight distribution in synthetic rubbers and latex systems. In personal care formulations, its thiol group interacts with keratin disulfide bonds, enabling conditioning and structural modification of hair. It also serves as a flavoring precursor in food applications, where trace sulfur compounds contribute characteristic aroma profiles.

This product is available in technical and food-grade qualities, with food-grade material conforming to FCC specifications. It is supplied in compliance with REACH regulations. Typical packaging includes drums and IBC containers, with documentation available to support regulatory submissions across EU markets.
