설명

일반 설명

Dimethyl sulfoxide is an organosulfur, commonly used as a polar solvent that can dissolve a wide range of polar and non-polar compounds. It is also utilized as a reaction reagent in several well-known processes, including swern oxidation, 2a pfitzner-moffatt oxidation, 2b, and the corey-chaykovsky reaction.

애플리케이션

Dimethyl sulfoxide (DMSO) has been used:

• in the preparation of ethyl 4-[¹⁸F]fluorobenzoate.
• in the culture medium for 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay.
• as a solvent in chemical synthesis.
• to dissolve and prepare stock solutions of small molecules, drugs, and chemical compounds for various assays and experiments.

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.
