Form Supplied in (1) white solid commercially available. Preparative Methods excess DMSO containing Copper(II) Chloride (or another copper catalyst) is treated with Chloramine-T trihydrate. (1) is obtained in 90% yield after aqueous EDTA workup and recrystallization from ethanol.The other A-tosylsulfoximines can be prepared by the tosylation of N-H sul-foximines with p-Toluenesulfonyl Chloride in the presence of base, but the two most useful and general methods are the oxidation of Af-tosylsulfilimines with basic Hydrogen Peroxide,  

Handling, Storage, and Precautions (1) is a highly crystalline compound with no known toxicity and unlimited shelf life.
