Leírás

Általános leírás

Dimethyl sulfoxide (DMSO) is a polar solvent. DMSO activated by various electrophiles (oxalyl chloride) has been used to oxidize various alcohols (primary, secondary, allylic, benzylic, hindered and bicyclic). Carbonyl compounds are formed as reaction products. It has been proposed as an alternate solvent for methyl cellosolve for use in ninhydrin reaction, due to its high stability.

Alkalmazás

Dimethyl sulfoxide (DMSO) has been used as a solvent in the high-throughput compound screening studies conducted on Mtb (Mycobacterium tuberculosis) H37Rv host cells.

Vigyázat

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
