| Toxicity | One of the most potent of the inhalational anesthetics, having a very high blood-gas partition coefficient and low vapor pressure at room temperature. Methoxyflurane is metabolized to a great extent (about 50-70%) in the liver and, as a consequence, there may be release of high concentrations of fluoride, sufficient to exceed the threshold for renal damage. Its use for sustained anesthesia is limited because of this renal toxicity and was discontinued around 1980. |

| Use | is a newer general inhalation anesthetic. Among the known inhaled anesthetics, the general anesthesia efficacy is the strongest, and there is a significant muscle relaxant effect. Currently, it is mostly used for general anesthesia. |
| production method | 1,2,-difluoro -1,1,2, 2-tetrachloroethane is rearranged into 1, 1-difluoro-1, 2,2, 2-tetrachloroethane, and then 1 molecule of CL2 is removed, and then added with methanol to obtain methoxyflurane. |
