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 mmHg 669 mmHg @ 20°C 731 mmHg @ 22°C 757 mmHg @ 22.8°C (boiling point;1atm) 764 mmHg @ 23°C 798 mmHg @ 24°C 869 mmHg @ 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 is nonflammable as defined by the requirements of International Electrotechnical Commission 601-2-13. Desflurane, USP is a colorless, volatile liquid below 22.8°C. Data indicate that desflurane, USP is stable when stored under normal room lighting conditions according to instructions. Desflurane, USP 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 does not corrode stainless steel, brass, aluminum, anodized aluminum, nickel plated brass, copper, or beryllium. Structure
