General description
二甲基亚砜(DMSO)是一种具有吸湿性、高极性的两亲性溶剂,可溶解多种化合物。DMSO对成牙细胞样细胞的牙髓组织修复相关活性的细胞毒性研究表明它产生了轻微的影响。它可与五氧化二磷一起参与碳水化合物的氧化,以得到醛糖和醛糖苷。DMSO可参与到一些部分乙酰化碳水化合物的氧化,并通过之后清除得到不饱和的衍生物。直链淀粉和支链淀粉在DMSO中的溶解度已得到评估。
Application
DMSO已用于制备DMSO-磷酸盐缓冲液,而它在一项研究中被用于溶解选择性的ETB (ET = 內皮素)受体拮抗剂。它已用于制霉菌素溶液的制备。
二甲基亚砜可用于合成以下物质:
- α, β−不饱和羰基糖衍生物。
- 将二级溴化物或烯烃转化为溴代醇。
- 由相应的酮合成α-羟基羰基。
Disclaimer
在室温下容易过冷并缓慢重融。 固化产品可以通过加热至室温来重新液化,而不会损害产品。
