Usage of Diphenyl sulfide
Diphenyl Sulfide (CAS 139‑66‑2) is an aromatic organosulfur building block. Thanks to its active sulfur‑ether structure, it is widely applied in fine‑chemical synthesis, UV‑curing materials, agrochemicals, pharmaceutical intermediates and dyestuff manufacturing. It acts as a key starting material for triaryl sulfonium photoinitiators, also functions as selective catalyst and metal extractant in various industrial processes.
1. UV‑Curing Materials Industry
Critical raw material for manufacturing riaryl sulfonium salt photoinitiators. These cationic photoinitiators are widely used for UV‑curable coatings, printing inks, adhesives and electronic photoresists.
2. Agrochemical Intermediates
Key intermediate for synthesis of fungicides, insecticides and miticides. It participates in the preparation of multiple crop‑protection active molecules for agricultural formulations.
3. Pharmaceutical Synthesis
4. Dyestuff & Pigment Intermediates
Applied for synthesizing sulfur‑containing dyes and functional colorants for coating and textile coloration industry.
5. Catalysis & Metal Extraction
Serves as selective catalyst for aromatic chlorination reactions. Work as solvent‑type extractant for selective separation & recovery of heavy‑metal ions in hydrometallurgy processes.
6. Organic Fine‑Chemical R&D
Fundamental thioether raw material for lab‑scale and pilot‑scale organic synthesis; can be oxidized into diphenyl sulfoxide and diphenyl sulfone for further downstream derivatives. Also used as additive for organic photovoltaic material research.
