Applications
Polymer Industry
PVC Stabilizer: Its metal chelating ability prevents PVC degradation by absorbing and stabilizing metal ions (often used with organic tin or calcium-zinc stabilizers).
Polyester Modifier: Introduces thioether groups into polyester chains to improve flexibility and dyeability.
Pharmaceuticals and Agrochemicals
Drug Synthesis: Intermediate for antibiotics (e.g., cephalosporin derivatives) and anticancer drugs (e.g., thiol-containing compounds).
Herbicide/Pesticide: Precursor for sulfide-based herbicides (e.g., thiadiazine derivatives) or insect repellents.
Water Treatment
Chelating Agent: Removes heavy metals (e.g., , ) from industrial wastewater via complexation.
Cosmetics and Dyes
Surfactant: Forms amphiphilic compounds with fatty alcohols for shampoos or emulsifiers.
Dye Intermediate: Synthesizes sulfur-containing dyes with improved fastness.
Organic Synthesis
Thioether Linker: Introduces thioether bridges in organic molecules for bioconjugation or polymer crosslinking.
