Halothane, sold under the brand name Fluothane among others, is a general anaesthetic. [5] It can be used to induce or maintain anaesthesia. [5] One of its benefits is that it does not increase the production of saliva, which can be particularly useful in those who are difficult to intubate. [5]
It is a semifluorinated alkane. [ 4 ] Perfluorohexyloctane has been available in multiple markets since 2015 under the brand names Evotears and Novatears, [ 5 ] and was additionally approved for medical use in the United States in May 2023 under the brand name Miebo.
Alkanes play a negligible role in higher organisms, with rare exception. Some yeasts, e.g., Candida tropicale, Pichia sp., Rhodotorula sp., can use alkanes as a source of carbon or energy. The fungus Amorphotheca resinae prefers the longer-chain alkanes in aviation fuel, and can cause serious problems for aircraft in tropical regions. [39]
Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C(CH 2) 5 CH 3 or C 7 H 16.When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).
An alkane is an acyclic saturated hydrocarbon. See Alkane. Alkanes as substituents are called alkyl groups Subcategories. This category has the following 5 ...
The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1 ] [ 2 ] Number of C atoms
Medical use of alkaloid-containing plants has a long history, and, thus, when the first alkaloids were isolated in the 19th century, they immediately found application in clinical practice. [206] Many alkaloids are still used in medicine, usually in the form of salts widely used including the following: [ 14 ] [ 207 ]
2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C 6 H 14.It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain.
