Methoxyflurane, its cas register number is 76-38-0. It also can be called Penthrane; Pentrane; Anecotan. Methoxyflurane is an extremely potent and highly lipid soluble anesthetic agent. Methoxyflurane (also known as penthrane) is an inhaled analgesic used for emergency pain relief. It is metabolised by the liver and excreted by the lungs, and it works by depressing the patient's central nervous system. Methoxyflurane is the relatively new full-body inhalation anesthetic. In the known inhalation anesthetic, it has the strongest performance of general anesthesia and has a clear role in muscles' relaxation. It is generally now used for light anesthesia.

Physical properties about Methoxyflurane are: (1)ACD/LogP: 1.941; (2)ACD/LogD (pH 5.5): 1.94; (3)ACD/LogD (pH 7.4): 1.94; (4)ACD/BCF (pH 5.5): 17.58; (5)ACD/BCF (pH 7.4): 17.58; (6)ACD/KOC (pH 5.5): 270.84; (7)ACD/KOC (pH 7.4): 270.84; (8)#H bond acceptors: 1; (9)#Freely Rotating Bonds: 2; (10)Index of Refraction: 1.383 ; (11)Molar Refractivity: 27.643 cm³; (12)Molar Volume: 118.508 cm³; (13)Polarizability: 10.959 10-24cm³; (14)Surface Tension: 23.0100002288818 dyne/cm; (15)Density: 1.392 g/cm³; (16)Flash Point: 10.637 °C; (17)Enthalpy of Vaporization: 32.975 kJ/mol; (18)Boiling Point: 104.999 °C at 760 mmHg; (19)Vapour Pressure: 35.0060005187988 mmHg at 25°C
