4. Applications

Industrial Uses

1. 1.Mining:
   • Flotation Agent: Collects sulfide minerals (e.g., Cu, Pb, Zn) in froth flotation.
   • Chelating Agent: Binds heavy metals (e.g., Cu²⁺, Fe³⁺) in hydrometallurgical processes.
2. 2.Rubber Industry:
   • Vulcanization Accelerator: Enhances cross-linking efficiency.
3. 3.Analytical Chemistry:
   • Spectrophotometry: Forms colored complexes with metals (e.g., Cu-DEDTC for UV-Vis detection).

Pharmaceuticals

• Antioxidant: Stabilizes formulations against oxidation.
• Reagent: Intermediate in synthesis of antifungal agents.

 

5. Handling and Storage

• Handling: Use in well-ventilated areas. Avoid contact with acids (releases toxic CS₂ gas).
• Storage: Keep in airtight, light-resistant containers at 2-25°C.
• Incompatibilities: Strong acids, oxidizers (e.g., HNO₃, H₂O₂).

 

6. Stability and Reactivity

• Decomposition Products: Carbon disulfide (CS₂), diethylamine, sulfur oxides.
• Light Sensitivity: Store in amber glass or opaque containers.
