Desflurane USP, liquid for inhalation a nonflammable liquid administered via vaporizer, is a general inhalation anesthetic. It is (±)1,2,2,2-tetrafluoroethyl difluoromethyl ether: Some physical constants are: Molecular weight 168.04 Specific gravity (at 20°C/4°C) 1.465 Vapor pressure in mm Hg 669 mm Hg @ 20°C 731 mm Hg @ 22°C 757 mm Hg @ 22.8°C (boiling point;1atm) 764 mm Hg @ 23°C 798 mm Hg @ 24°C 869 mm Hg @ 26°C Partition coefficients at 37°C: Blood/Gas 0.424 Olive Oil/Gas 18.7 Brain/Gas 0.54 Mean Component/Gas Partition Coefficients Polypropylene (Y piece) 6.7 Polyethylene (circuit tube) 16.2 Latex rubber (bag) 19.3 Latex rubber (bellows) 10.4 Polyvinylchloride (endotracheal tube) 34.7 Desflurane USP, liquid for inhalation is nonflammable as defined by the requirements of International Electrotechnical Commission 601-2-13. Desflurane USP, liquid for inhalation is a colorless, volatile liquid below 22.8°C. Data indicate that Desflurane USP, liquid for inhalation is stable when stored under normal room lighting conditions according to instructions. Desflurane USP, liquid for inhalation is chemically stable. The only known degradation reaction is through prolonged direct contact with soda lime producing low levels of fluoroform (CHF 3 ). The amount of CHF 3 obtained is similar to that produced with MAC-equivalent doses of isoflurane. No discernible degradation occurs in the presence of strong acids. Desflurane USP, liquid for inhalation does not corrode stainless steel, brass, aluminum, anodized aluminum, nickel plated brass, copper, or beryllium. desflurane-structure
