설명

일반 설명

Dimethyl sulfoxide (DMSO) is a polar organic 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. Due to its higher stability, it has been proposed as an alternate solvent for methyl cellosolve for use in ninhydrin reaction.

애플리케이션

Suitable for HPLC, spectrophotometry, environmental testing

주의사항

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