CAS Registry Number: 75-19-4. Chemical structure: This structure is also available as a 2d Mol file or as a computed 3d SD file. The 3d structure may be viewed using Java or Javascript . Other names: Trimethylene; Trimethylene (cyclic); UN 1027; Cyclopropnane. Permanent link for this species. Cyclopropane is the cycloalkane with the molecular formula (CH 2) 3, consisting of three methylene groups (CH 2) linked to each other to form a triangular ring.The small size of the ring creates substantial ring strain in the structure. Cyclopropane itself is mainly of theoretical interest but many of its derivatives - cyclopropanes - are of commercial or biological significance. Cyclopropane is a colorless gas with a petroleum-like odor. It is shipped as a liquid at 4-6 atms. It is easily ignited. The vapors are heavier than air. Contact with the liquid may cause frostbite. It can asphyxiate by the displacement of air and has a narcotic effect in high concentration (formerly used as an anesthetic gas). Cyclopropane is somewhat more reactive than the corresponding open-chain alkane propane, C 3 H 8. Other cycloalkanes make up a part of ordinary gasoline. Several unsaturated cyclic hydrocarbons, having the general formula C 10 H 16, occur in certain fragrant natural oils that are distilled from plant materials. These hydrocarbons are called Cyclopropane is considered to be one of the smallest cycloalkanes, and most of this class of members are said to be more stable in nature. Some common examples of cycloalkanes are the cyclopentane, Cyclobutane, cyclohexane, and cycloheptane, cyclooctane, etc as shown below in the image. The number of carbon atoms present in the compound decides Cyclopropane, explosive, colourless gas used in medicine since 1934 as a general anesthetic. Cyclopropane is nonirritating to mucous membranes and does not depress respiration. Induction of and emergence from cyclopropane anesthesia are usually rapid and smooth.
