Trimethylsulfoxonium Bromide

Trimethylsulfoxonium bromide (CAS 25596-24-1) is a versatile sulfoxonium salt widely employed as a methylene transfer reagent in organic synthesis. It is the bromide counterpart of the more common iodide, offering distinct solubility and reactivity profiles that make it a preferred choice in certain alkylation and cyclopropanation reactions. Supplied as a white crystalline solid with ≥98% purity, it is suitable for both laboratory-scale development and industrial production.

Our material is produced under controlled conditions and undergoes rigorous quality testing to ensure consistent performance in demanding synthetic applications. Each batch is accompanied by a certificate of analysis (COA), and technical documentation is available to support process optimization and scale-up.

Synonyms: Trimethyloxosulfonium bromide, (Bromodimethylsulfonium)methanide, Dimethylsulfoxonium methylide bromide, TMSOB

Applications

• Methylenation and cyclopropanation reactions in pharmaceutical intermediates
