Chemical and Physical Properties
Sterigmatocystin crystallises as pale yellow needles and is readily soluble in methanol, ethanol, acetonitrile, benzene, and chloroform. It reacts with hot ethanolic KOH and is methylated by methyl sulphate and methyl iodide. Methanol or ethanol in acid produces dihydroethoxysterigmatocystin.

Famous quotes containing the words chemical, physical and/or properties:
“We are close to dead. There are faces and bodies like gorged maggots on the dance floor, on the highway, in the city, in the stadium; they are a host of chemical machines who swallow the product of chemical factories, aspirin, preservatives, stimulant, relaxant, and breathe out their chemical wastes into a polluted air. The sense of a long last night over civilization is back again.”
—Norman Mailer (b. 1923)
“Parents’ accepting attitudes can help children learn to be open and tolerant. Parents can explain unfamiliar behavior or physical handicaps and show children that the appropriate response to differences should be interest rather than revulsion.”
—Dian G. Smith (20th century)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
