Description

Diphenyl Sulfide (CAS 139-66-2) is a high-purity organic sulfur compound with the molecular formula C₁₂H₁₀S. This aromatic sulfide, also known as phenylsulfanylbenzene, is characterized by its clear to pale yellow appearance and distinct odor. It is widely utilized in organic synthesis, material science, and pharmaceutical research due to its stability and reactivity as a sulfur-containing building block. With a melting point of -40°C and boiling point of 296°C, it is soluble in organic solvents like ethanol and ether but insoluble in water. Our product is rigorously tested for purity (≥98% by GC) and is supplied in sealed containers to ensure optimal shelf life and performance. Ideal for use as a ligand precursor, cross-coupling agent, or intermediate in the synthesis of advanced materials.
