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 ...

It is hygroscopic when exposed to air. [1] Modern texts refer to the choline salt of the natural form of tartaric acid , that is, the salt called choline dextrobitartrate, choline (2 R ,3 R )-bitartrate or choline L-(+)-bitartrate.
Starting from the 1960s, it received a shortened name of mesylic acid [7] after the term for the "mesyl" group coined by Helferich et al. in 1938. [ 8 ] In 1967, the Pennwalt Corporation (USA) developed a different process for dimethylsulfide (as a water-based emulsion) oxidation using chlorine , followed by extraction-purification.
Words as words: Deuce means two, or "deuce" means "two", whichever will be clearer in context (consider an article with many quotations, or an article full of italicized foreign terms). See Wikipedia:Manual of Style: "Words as words" subsection for more information.
Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them.
