What is Isooctyl thioglycolate?
Isooctyl thioglycolate (CAS 25103-09-7), also known as isooctyl mercaptoacetate, is a sulfur-containing ester used as a reactive intermediate and functional additive.
Where is Isooctyl thioglycolate used?
- Polymer and PVC processing: co-stabilizer component and plasticizing modifier
- Rubber: vulcanization chemistry influence and softening agent in specialty elastomer blends
- Lubricants and metalworking fluids: sulfur-active functionality for extreme-pressure and boundary lubrication
- It serves as a monomer or chain transfer agent in free-radical polymerization.
Commercial specifications
- Purity specifications typically confirmed by GC analysis
- Packaging: drums to IBC containers
