Cyclopentane is also used in the manufacture of synthetic resins and rubber adhesives. [citation needed] Cyclopentane is a minor component of automobile fuel, with its share in US gasoline varying between 0.2 and 1.6% in early 1990s [8] and 0.1 to 1.7% in 2011. [9] Its research and motor octane numbers are reported as 101 or 103 and 85 or 86 ...
1,2,3,4,5-Cyclopentanepentol, also named cyclopentane-1,2,3,4,5-pentol or 1,2,3,4,5-pentahydroxycyclopentane is a chemical compound with formula C 5 H 10 O 5 or (–CHOH–) 5, whose molecule consists of a ring of five carbon atoms (a cyclopentane skeleton), each connected to one hydrogen and one hydroxyl group.

Gonane is a significant chemical compound in the family of steroids because its structure comprises four hydrocarbon rings fused together, consisting of three cyclohexane units and one cyclopentane, which is often referred to as the "steroid nucleus" and serves as the parent compound for steroids.
The C 6 core of methylcyclopentane is not perfectly planar and can pucker to alleviate stress in its structure. [7] The conversion of methylcyclopentane to benzene is a classic aromatization reaction, specifically a dehydroisomerization. This platinum (Pt)-catalyzed process is practiced on scale in the production of gasoline from petroleum.
Cyclopentane (CAS 287-92-3) Methylcyclobutane (CAS 598-61-8) Cyclopropanes. Ethylcyclopropane (CAS 1191-96-4) 1,1-Dimethylcyclopropane (CAS 1630-94-0)
It is a saturated cyclopentane with three methyl substituents branching off carbons 1,2, and 3. The methyl groups off carbons 1 and 3 are trans with respect to each other, while the methyl group off carbon 2 has undefined stereochemistry , allowing it to be either cis or trans with respect to methyl 1 or 3.
Cyclopentadiene is an organic compound with the formula C 5 H 6. [6] It is often abbreviated CpH because the cyclopentadienyl anion is abbreviated Cp −.. This colorless liquid has a strong and unpleasant odor.
The chemical structure is exemplified by iridomyrmecin, a defensive chemical produced by the ant genus Iridomyrmex, for which iridoids are named. Structurally, they are bicyclic cis-fused cyclopentane-pyrans. Cleavage of a bond in the cyclopentane ring gives rise to a subclass known as secoiridoids, such as oleuropein and amarogentin.
