==History==
Valeric acid is a minor constituent of the perennial flowering plant [[Valerian (herb)|valerian]] (''Valeriana officinalis''), from which it gets its name.<ref name=EB1911>{{cite EB1911 |wstitle=Valeric Acid |volume=27 |page=859}}</ref> The dried root of this plant has been used medicinally since antiquity.<ref>{{cite journal |doi=10.2478/v10136-009-0002-z |doi-access=free |title=Biomedically relevant chemical constituents of ''Valeriana officinalis'' |year=2010 |last1=Patočka |first1=Jiří |last2=Jakl |first2=Jiří |journal=Journal of Applied Biomedicine |volume=8 |pages=11–18 }}</ref> The related [[3-Methylbutanoic acid|isovaleric acid]] shares its unpleasant odor and their chemical identity was investigated  by oxidation of the components of [[fusel alcohol]], which includes the five-carbon [[amyl alcohol]]s.<ref>{{cite journal |doi=10.1039/JS8682100074 |title=On the isomeric forms of valeric acid |year=1868 |last1=Pedler |first1=Alexander |journal=Journal of the Chemical Society |volume=21 |pages=74–76 |url=https://zenodo.org/record/2175638 }}</ref>
Valeric acid is one volatile component in swine manure.  Other components include other carboxylic acids, [[skatole]], [[trimethyl amine]], and [[isovaleric acid]].<ref>{{cite journal|doi=10.1016/j.chemosphere.2012.04.061|pmid=22682363|title=Volatile organic compounds at swine facilities: A critical review|journal=Chemosphere|volume=89|issue=7|pages=769–788|year=2012|last1=Ni|first1=Ji-Qin|last2=Robarge|first2=Wayne P.|last3=Xiao|first3=Changhe|last4=Heber|first4=Albert J.|bibcode=2012Chmsp..89..769N}}</ref> It is also a flavor component in some foods.<ref>{{cite journal |doi=10.1080/00021369.1970.10859653 |title=Studies on Flavor Components of Roasted Barley |year=1970 |last1=Wang |first1=Pao-Shui |last2=Kato |first2=Hiromichi |last3=Fujimaki |first3=Masao |journal=Agricultural and Biological Chemistry |volume=34 |issue=4 |pages=561–567 }}</ref>
