Cyclopentanone
Cyclopentanone is the organic compound with the formula (CH2)4CO. This cyclic ketone is a colorless volatile liquid. Preparation Upon treatment with barium hydroxide at elevated temperatures, adipic acid undergoes ketonization to give cyclopentanone: :(CH2)4(CO2H)2 → (CH2)4CO + H2O + CO2 Uses Cyclopentanone is common precursor to fragrances, especially those related to jasmine and jasmone. Examples include 2-pentyl- and 2-heptylcyclopentanone.Johannes Panten and Horst Surburg "Flavors and Fragrances, 2. Aliphatic Compounds" in Ullmann's Encyclopedia of Industrial Chemistry, 2015, Wiley-VCH, Weinheim. It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital. Cyclopentanone is also used to make cyclopentamine, the pesticide pencycuron, and pentethylcyclanone Pentethylcyclanone is an antitussive medication A medication (also called medicament, medicine, pharmaceutical drug, medicinal drug or simply drug) is a drug used to diagnose, c ...

Ketone
In organic chemistry, a ketone is a functional group with the structure R–C(=O)–R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group –C(=O)– (which contains a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' is methyl), with the formula . Many ketones are of great importance in biology and in industry. Examples include many sugars (ketoses), many steroids (e.g., testosterone), and the solvent acetone. Nomenclature and etymology The word ''ketone'' is derived from ''Aketon'', an old German word for ''acetone''. According to the rules of IUPAC nomenclature, ketone names are derived by changing the suffix ''-ane'' of the parent alkane to ''-anone''. Typically, the position of the carbonyl group is denoted by a number, but traditional nonsystematic names are still generally used for the most important ketones, for example acetone and benzophenone. These nonsystematic names are considere ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

3-Methyl-2-butanone
3-Methyl-2-butanone (methyl isopropyl ketone, MIPK) is a ketone and solvent of minor importance. It is comparable to MEK ( Methyl ethyl ketone), but has a lower solvency and is more expensive.{{citation , author=Dieter Stoye , contribution=Solvents , title=Ullmann's Encyclopedia of Industrial Chemistry ''Ullmann's Encyclopedia of Industrial Chemistry'' is a major reference work related to industrial chemistry by Chemist Fritz Ullmann, first published in 1914, and exclusively in German as "Enzyklopädie der Technischen Chemie" until 1984.
