2-Pentanone or methyl propyl ketone (MPK) is a ketone and solvent of minor importance. It is comparable to methyl ethyl ketone , but has a lower solvency and is more expensive. [ 5 ] It occurs naturally in Nicotiana tabacum (Tobacco) [ 6 ] and blue cheese as a metabolic product of Penicillium mold growth.
Examples include 2-pentyl- and 2-heptylcyclopentanone. [4] It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital. [5] Cyclopentobarbital, a drug made from cyclopentanone. Cyclopentanone is also used to make cyclopentamine, the pesticide pencycuron, and pentethylcyclanone. [5]
In contrast to that, the other stereo isomers show an unspecific fruity odor, the odor detection threshold are 11.2 ng·l −1 and 14.9 ng·l −1 which is much higher. [ 2 ] [ 3 ] The tenacity on blotter , the time during which the compound is smellable with unchanged characteristics, [ 4 ] : 51 is reported to be three weeks.
If there are multiple functional groups of the same type, either prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) The N position indicator for amines and amides comes before "1", e.g., CH 3 CH(CH 3)CH 2 NH(CH 3) is N,2-dimethylpropanamine.
Cypenamine is a homolog of tranylcypromine, containing an expanded alicyclic ring that is two methylene units larger than the highly strained/reactive cyclopropane. The cyclohexane homologue has been reported, although the LD 50 s were all less than for plain amphetamine, it was still a functional stimulant.

Methylcyclopentane is an organic compound with the chemical formula CH 3 C 5 H 9.It is a colourless, flammable liquid with a faint odor. It is a component of the naphthene fraction of petroleum usually obtained as a mixture with cyclohexane.
Methylcyclopentadiene is any of three isomeric cyclic dialkenes with the formula C 5 MeH 5 (Me = CH 3).These isomers are the organic precursor to the methylcyclopentadienyl ligand (C 5 H 4 Me, often denoted as Cp′), commonly found in organometallic chemistry.
