C11H16O (164.1201)


(Z)-3-Methyl-2-(2-pentenyl)-2-cyclopenten-1-one is found in citrus. (Z)-3-Methyl-2-(2-pentenyl)-2-cyclopenten-1-one occurs in peppermint oil, green tea and bergamot oranges (Citrus bergamia).Jasmone is a natural organic compound extracted from the volatile portion of the oil from jasmine flowers. It is a colorless to pale yellow liquid that has the odor of jasmine. Jasmone can exist in two isomeric forms with differing geometry around the pentenyl double bond, cis-jasmone and trans-jasmone. The natural extract contains only the cis form, while synthetic material is often a mixture containing both forms, with the cis form predominating. Both forms have similar odors and chemical properties. (Wikipedia Jasmone is a cyclic ketone. Jasmone is a natural product found in Lonicera japonica, Pulicaria arabica, and other organisms with data available. Occurs in peppermint oil, green tea and bergamot oranges (Citrus bergamia) Cis-Jasmone is a plant-derived natural product. Cis-Jasmone is constitutively released by many flowers and sometimes by leaves as an attractant for pollinators or as a chemical cue for host location by insect flower herbivores. Cis-Jasmone treatment of crop plants not only induces direct defense against herbivores, but also induces indirect defense by releasing VOCs that attract natural enemies[1].

Cyclohexanone

Cyclohexanone homopolymer

C6H10O (98.0732)


Cyclohexanone is a food flavourant. Present in various plant spp. e.g. Cistus ladaniferus (labdanum). Cyclohexanone is a colorless oily liquid with an odor resembling acetone and peppermint. Cyclohexanone is occasionally found as a volatile component of human urine. Biological fluids such as blood and urine have been shown to contain a large number of components, some of them volatiles (low boiling point) apparently present in all individuals, while others such are much more variable. In some cases differences up to an order of magnitude are observed. Although some of these changes may have dietary origins, others seem to be characteristic of the individual. Cyclohexanone is obtained through oxidation of cyclohexane or dehydrogenation of phenol. Approx. 95\\% of its manuf. is used for the production of nylon. Information on toxicity to human beings is fragmentary. Acute exposure is characterized by irritation of the eyes, nose, and throat. In two persons, drowsiness and renal impairment were found; Like cyclohexanol, cyclohexanone is not carcinogenic and is only moderately toxic, with a TLV of 25 ppm for the vapor. It is an irritant.; The great majority of cyclohexanone is consumed in the production of precursors to Nylon 66 and Nylon 6. About half of the worlds supply is converted to adipic acid, one of two precursors for nylon 66. For this application, the KA oil (see above) is oxidized with nitric acid. The other half of the cyclohexanone supply is converted to the oxime. In the presence of sulfuric acid catalyst, the oxime rearranges to caprolactam, a precursor to nylon 6:; however, there were embryotoxic effects and influence on reproduction Cyclohexanone is well absorbed through the skin, respiratory tract, and alimentary tract. The main metabolic pathway leads to cyclohexanol, which is excreted in urine coupled with glucuronic acid. A high correlation was found between the concentration of cyclohexanone in the working environment and its concentration in urine. Cyclohexanone is formed from the hydrocarbons cyclohexane and 1-, 2-, and 3-hexanol. A patients case report documents the development of anosmia (an olfactory disorder) and rhinitis caused by occupational exposure to organic solvents, including cyclohexanone (PMID: 10476412, 16925936, 16477465); however, these workers were also exposed to other compounds. Hepatic disorders were found in a group of workers exposed for over five years. In animals, cyclohexanone is characterized by relatively low acute toxicity (DL50 by intragastric administration is approx. 2 g/kg body wt.). Effects on the central nervous system (CNS) were found (narcosis), as well as irritation of the eyes and skin. Following multiple administration, effects were found in the CNS, liver, and kidneys as well as irritation of the conjunctiva. Mutagenic and genotoxic effects were found, but no teratogenic effects were detected Cyclohexanone is a colorless oily liquid with an odor resembling acetone and peppermint.

Cyclopentanone

3-Acetyl-6-methyl-pyran-2,4(3H)-dione

C5H8O (84.0575)


Cyclopentanone belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Cyclopentanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, cyclopentanone is considered to be an oxygenated hydrocarbon lipid molecule. Cyclopentanone is a cyclic ketone, structurally similar to cyclopentane, consisting of a five-membered ring containing a ketone functional group. Cyclopentanone is a colorless liquid organic compound with a peppermint-like odor. Cyclopentanone is found in various foods, including potato and tomato, and cooked foods, e.g. butter, meats, coffee, roasted peanut. Cyclopentanone is also used as a flavouring ingredient. Found in various foods, including potato and tomato, and cooked foods, e.g. butter, meats, coffee, roasted peanut. Flavouring ingredient
