Deuterated DMSO, also known as dimethyl sulfoxide-d 6, is an isotopologue of dimethyl sulfoxide (DMSO, (CH 3) 2 S=O)) with chemical formula ((CD 3) 2 S=O) in which the hydrogen atoms ("H") are replaced with their isotope deuterium ("D"). Deuterated DMSO is a common solvent used in NMR spectroscopy.
There is no standard quantitative definition of hygroscopicity, so generally the qualification of hygroscopic and non-hygroscopic is determined on a case-by-case basis. For example, pharmaceuticals that pick up more than 5% by mass, between 40 and 90% relative humidity at 25 °C, are described as hygroscopic, while materials that pick up less ...

A hygroscopic substance used to induce or sustain a state of dryness or desiccation (i.e. the absence of moisture) in its vicinity by abstracting water molecules from other substances. Desiccants come in many different forms and work by many different principles, ranging from simple absorption to the chemical bonding of water molecules.

Dimethyl sulfone (DMSO 2) is an organosulfur compound with the formula (CH 3) 2 SO 2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert ...
