| Property | Value / Note |
|---|---|
| Physical state | Oily, colorless to pale-yellow liquid with strong aromatic sulfur odor. |
| Density (20 °C) | ≈ 1.13 g/cm³ |
| Odour threshold | Extremely low — detectable at ppb levels (odor nuisance risk). |
| Decomposition | On burning → SO₂ + H₂S + phenyl residues; avoid hot surfaces > 300 °C. |
| Typical sources | Organic sulfidic by-products from thio-ether synthesis, lubricant additives, coal tar distillation, and pyrolysis gas streams. |
