詳細

詳細

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.

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.

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。
