Dimethyl Sulfoxide
methyl sulfoxide, DMSO laboratory grade (CH3)2SO
F.W. 78.13
45
Technical Note: When DNA is heated in the presence of sufuric acid, the deoxyribose is converted to a molecule that binds with diphenylamine to form a dark blue-black complex. The intensity of the color is proportional to the amount of deoxyribose present. CAS No. 122-39-4
D0061 100 g
 HAZARD ALERT: Flammable; toxic by ingestion. LD50 >500 mg/kg.
Storage: Organic #2
Disposal: #5
Shelf Life: Good, if stored safely.
Soluble: Slightly soluble in water and alcohol; soluble in dilute inorganic acids.
Color and Odor: Moist, reddish-orange solid; odorless.
CAS No. 119-26-6
Technical Note: Contains 30–35% water as a stabilizer. Dry solid is shock-sensitive. Used to test for and identify carbonyl compounds.
