Product Name:3,5-Dithia-1,7-heptanediol
English Name:3,5-Dithia-1,7-heptanediol
CAS No.:44860-68-6
Aliases:3,5-dithiaoctane-1,8-diol, 2,2'-thiobis(ethylthio)ethanol, 3,5-dithia-1,7-dihydroxyheptane
Molecular Formula:C5H12O2S2
Physical Properties:Colorless to pale yellow transparent liquid with a slight characteristic odor. Density: approximately 1.2 g/cm³; boiling point: approximately 299.9°C (760 mmHg); flash point: approximately 110°C. Soluble in alcohols, ketones, and other organic solvents; slightly soluble in water. The molecule contains two hydroxyl groups and two thioether linkages, combining the chemical reactivity of alcohols with the coordination ability of thioethers.
Uses:Primarily used as an organic synthesis intermediate for the production of polyurethanes, epoxy resin curing agents, and polymer crosslinkers. Its thioether structure imparts excellent oil resistance and anti-aging properties to materials, making it applicable in specialty coatings, adhesives, and rubber modification. Additionally, it serves as a chelating ligand for precious metal extraction and surface treatment.
Technical Specifications:
Purity: ≥98.0% (GC)
Appearance: colorless to pale yellow transparent liquid
Water content: ≤0.5% (K-F method)
Density (20°C): 1.20±0.02 g/cm³
Boiling point: 299.9°C (760 mmHg)
