Product Description

Trimethylsulfoxonium iodide is a widely used sulfoxonium salt and a key reagent in organic synthesis.
It is primarily utilized for epoxidation and carbonyl methylene insertion reactions when combined with strong bases, making it a valuable building block in:

• Pharmaceutical manufacturing

• Fine chemical synthesis

• Advanced material research

It is a stable and highly efficient ylide precursor, enabling selective formation of epoxides and functionalized alkenes under controlled reaction conditions.

Key Applications

✔ Epoxidation reagent — especially for carbonyl → oxirane conversion
✔ Ylide precursor in Johnson–Corey–Chaykovsky reactions
✔ Intermediate for active pharmaceutical ingredients (APIs)
✔ Fine chemical and custom research synthesis

Typical use in the pharmaceutical industry includes synthesis of:

• β-lactams

• Chiral epoxy derivatives

• Heterocyclic drug intermediates

It is also widely adopted in academic and industrial R&D settings due to its dependable reactivity profile.
