2-Pentanone or methyl propyl ketone (MPK) is a minor ketone and solvent. It is comparable to methyl ethyl ketone, but has lower solvency power and is more expensive. [5] It occurs naturally in tobacco (Nicotiana tabacum)[6] and blue cheese as a metabolite of Penicillium growth.

2-Pentanone is a natural product that occurs in Vitis rotundifolia, Aloe africana, and other organisms for which data are available.

Pentan-2-one is a pentanone with an oxo substituent at the 2-position. It functions as a plant metabolite. It is methyl ketone and pentanone.

2-Pentanone, also known as ethylacetone or fema 2842, 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 is a hydrogen atom). Ketones with one or more α-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. 2-Pentanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Therefore, 2-pentanone is considered to be an oxygenated hydrocarbon lipid molecule. 2-Pentanone is a sweet, alcoholic and banana-like compound. On average,
