Chain transfer agent

Raft Agent

Through our long history of manufacturing rubber chemicals and other organosulfur compounds, we have built a “resource-recycling production model” based on the following three technologies.

Technology for the safe handling of carbon disulfide, a special flammable material, as a raw material.
Technology for handling odorous substances such as thiol compounds generated during reactions.
Technology to view byproduct hydrogen sulfide as a resource, and to refine, commercialize, and produce it in-house.

We have started handling thiocarbonyl compounds, which are widely used in radical chain transfer agents for RAFT process.
We can provide speedy services from laboratory to mass production of thiocarbonyl compounds.
Custom synthesis of compounds not listed here is also available.
