China and India are the leading exporters of phenyl sulfoxide (CAS 945-51-7), accounting for the majority of global export volume in recent years, while the United States, Germany, and Japan represent the largest importing markets. Trade flows have remained relatively stable since 2022, with modest growth in imports by EU-based pharmaceutical intermediaries coinciding with steady phenyl sulfoxide prices.
Phenyl sulfoxide is a white to off-white crystalline solid at room temperature, with a mild odor and low volatility; it melts at approximately 48–50 °C and decomposes before boiling. It is an aromatic organosulfur compound, specifically a sulfoxide, featuring a sulfur atom doubly bonded to oxygen and singly bonded to a phenyl group and a methyl group. Primarily employed as a versatile synthetic intermediate, it serves in the preparation of sulfones, chiral ligands, and functionalized sulfur-containing molecules. Its main industrial applications are in pharmaceutical synthesis—particularly in the development of bioactive compounds—and in agrochemical research for constructing novel active ingredients.
