'''2-펜탄온'''({{llang|en|2-pentanone}}) 또는 '''메틸 프로필 케톤'''({{llang|en|methyl propyl ketone}}, '''MPK''')은 [[케톤]]이며 그다지 중요하지 않은 [[용매]]이다. 2-펜탄온은 [[메틸 에틸 케톤]]과 비슷하지만 용해력이 낮고 가격이 더 비싸다.<ref>{{인용| author=Dieter Stoye | contribution=Solvents | title=Ullmann's Encyclopedia of Industrial Chemistry | edition=7th | publisher=Wiley | year=2007 | pages=55-56}}</ref> 2-펜탄온은 [[푸른곰팡이]] 생장에서의 [[대사 산물]]로<ref>{{웹 인용|url=http://www.webexhibits.org/butter/compounds-methylKetones.html|title=WebExhibits: Methyl ketones}}</ref> [[담배 (종)|담배]](''Nicotiana tabacum'')<ref>{{인용| author=T.
