설명

일반 설명

Dimethyl sulfoxide (DMSO) is a hygroscopic, high polarity amphiphilic solvent with an ability to dissolve many compounds.[1] Cytotoxic study of DMSO on the pulp tissue repair-related activity of odontoblast-like cells showed it produced minor effects.[2] Along with phosphorus pentaoxide it participates in the oxidation of carbohydrates to afford aldosuloses and aldosiduloses.[3] DMSO participates in the oxidation of some partially-acetylated carbohydrates followed by elimination to afford unsaturated, derivatives.[4] Solubility of amylose and amylopectin in DMSO has been evaluated.[5]

애플리케이션

DMSO has been used to prepare the DMSO-phosphate buffer solution, which was used to dissolve the selective ET_B (ET = endothelin) receptor antagonist in a study.[6] It has been used for the preparation of nysatin solution.[7]

Dimethyl sulfoxide may be used in the synthesis of the following:

• α, β−Unsaturated carbonyl sugar derivatives.[8]
• Conversion of secondary bromides or olefins to bromohydrin.[9]
• Synthesis of α-hydroxycarbonyls from corresponding ketones.[10]

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.
