trimethylsulfoxonium Iodide (CAS NO : 1774-47-6)

Trimethylsulfoxonium iodide (CAS 1774-47-6) is an essential reagent in the API intermediates market, serving as the primary precursor for dimethyloxosulfonium methylide used in Corey-Chaykovsky cyclopropanation and epoxidation. As a leading bulk chemical supplier, we observe that CDMOs are increasingly integrating these high-purity fine chemicals into their specialized synthetic toolkits to produce complex heterocyclic scaffolds for oncology and antiviral therapeutics (Pharma/API purity 99%). Trimethyloxosulfonium iodide (CAS 1774-47-6) remains a critical building block for the synthesis of azole antifungals, such as fluconazole, where stereoselective methylene transfer is paramount. Current global sourcing shifts favor manufacturers who provide robust custom synthesis services and maintain rigorous regulatory compliance to meet the evolving ICH Q3A(R2) impurity profile standards (Pharma/API purity 99%). Sulfoxonium, trimethyl-, iodide (1:1) (CAS 1774-47-6) is gaining traction in industrial use for the development of advanced ionic liquids and as a selective methylating agent in polymer science. Reliability in the supply chain for these high-purity fine chemicals is essential as the industry moves toward sustainable green chemistry and optimized atom-efficient processes (General Industry purity 98%). We are an established global intermediates supplier with >= 99% purity, ensuring minimal carry-over of impurities in the final API, and a broad range of various pharmaceutical intermediates for API manufacturers and finished formulators, providing comprehensive analytical (HPLC/NMR/MS) and supporting trimethylsulfoxonium iodide COA/TDS/SDS region-specific regulatory support, reliable lead times, and worldwide supply chain capabilities.
