What is Carbon disulfide?
Carbon disulfide (CAS 75-15-0), also known as CS2 and carbon bisulphide, is a high-purity industrial solvent used in chemical manufacturing and analytical processes.
Where is Carbon disulfide used?
- Specialty chemicals: extraction and reaction medium for sulfur, phosphorus and halogen compounds
- Agrochemicals: intermediate in the synthesis of xanthates, dithiocarbamates and thiuram-based fungicides and accelerators
- Flavor and fragrance: solvent for GC/MS headspace analysis and aroma extraction
- Viscose rayon and cellophane: reacts with cellulose and sodium hydroxide to form cellulose xanthate
- Rubber processing: solvent for sulfur compounds and accelerator blends during compounding and quality control testing
Good to know: Buyers should confirm purity thresholds and stabilizer content before purchase.
Commercial specifications
- Clear liquid in drums, IBCs and bulk tanker quantities
- High-purity and reagent-grade specifications are available for analytical applications

What are the physical properties of Carbon disulfide?
Melting Point -111.5 °C
Boiling Point 46 °C @ Press: 760 Torr
Density 1.2632 g/cm³ @ Temp: 20 °C
Flash Point −29 °F
Appearance Carbon disulfide is a highly refractive, flammable liquid; which, in pure form has a sweet odor and in commercial and reagent grades has a foul smell. It can be detected by odor at about 1 ppm but the sense of smell fatigues rapidly and, therefore, odor does not serve as a good warning property.
Color ≤10(APHA)
Odor Cabbage-like odor detectable at 0.016 to 0.42 ppm (mean = 0.2 ppm)
Form Liquid
Water Solubility 2.9 g/L (20 ºC)
Vapor Pressure 5.83 psi ( 20 °C)
Refractive Index n 20/D 1.627(lit.)
