Chemical and Physical Properties
Further information: OrganofluorineWith a molecular formula of C3H4Cl2F2O and a condensed structural formula of CHCl2CF2OCH3, the International Union of Pure and Applied Chemistry (IUPAC) name for methoxyflurane is 2,2-dichloro-1,1-difluoro-1-methoxyethane. It is a halogenated ether in form of a clear, colorless liquid, and its vapor has a strong fruity aroma. It is miscible with ethanol, acetone, chloroform, diethyl ether, and fixed oils. It is soluble in rubber.
With a minimum alveolar concentration (MAC) of 0.2%, methoxyflurane is an extremely potent anesthetic agent. It is a powerful analgesic agent at well below full anesthetic concentrations. Because of its low volatility and very high boiling point (104.8 °C at 1 atmosphere), methoxyflurane has a low vapor pressure at ambient temperature and atmospheric pressure. It is therefore quite difficult to vaporize methoxyflurane using conventional anesthetic vaporizers.

The carbon–fluorine bond, a component of all organofluorine compounds, is the strongest chemical bond in organic chemistry. Furthermore, this bond becomes shorther and stronger as more fluorine atoms are added to the same carbon on a given molecule. Because of this, fluoroalkanes are some of the most chemically stable organic compounds.

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)
“A more problematic example is the parallel between the increasingly abstract and insubstantial picture of the physical universe which modern physics has given us and the popularity of abstract and non-representational forms of art and poetry. In each case the representation of reality is increasingly removed from the picture which is immediately presented to us by our senses.”
—Harvey Brooks (b. 1915)
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
