詳細

詳細

Dimethyl sulfoxide (DMSO) is a polar solvent.[1] 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.[2] It has been proposed as an alternate solvent for methyl cellosolve for use in ninhydrin reaction, due to its high stability.[3]

アプリケーション

Dimethyl sulfoxide (DMSO) has been used as a solvent in the high-throughput compound screening studies conducted on Mtb (Mycobacterium tuberculosis) H37Rv host cells.[4]

注意

容易に過冷却状態となり、室温で徐々に再融解します。凝固している場合は室温に放置すると、劣化させることなく液体に戻すことができます。
