Cyclopentanone is common precursor to fragrances, especially those related to jasmine and jasmone.Examples include 2-pentyl- and 2-heptylcyclopentanone. [4] It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital.
Its freezing point is −94 °C and its boiling point is 49 °C. Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more carbon rings. It is formed by cracking cyclohexane in the presence of alumina at a high temperature and pressure. It was first prepared in 1893 by the German chemist Johannes Wislicenus. [5]

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
Melting point: −63.68 °C (−82.62 °F; 209.47 K) Boiling point: 115.3 °C (239.5 °F; 388.4 K) ... Flash point: 41 °C (106 °F; 314 K) Autoignition
The hydroxyl group (OH) is the active site of many reactions. The ester formed from 1-pentanol and butyric acid is pentyl butyrate, which has an apricot-like odor.The ester formed from 1-pentanol and acetic acid is amyl acetate (also called pentyl acetate), which has a banana-like odor.
