3-Methylbutanoic acid, or more commonly isovaleric acid, is a natural fatty acid found in a wide variety of plants and essential oils. Isovaleric acid is clear colorless liquid that is sparingly soluble in water, but extremely soluble in most common organic solvents.

Isovaleric acid has a strong pungent cheesy or sweaty smell, but its volatile esters have pleasing scents and are used widely in perfumery. It has been proposed that it is the anticonvulsant agent in valerian. [M. Eadie Epilepsia 45(11) p1338 2004, http://www.blackwell-synergy.com/doi/pdf/10.1111/j.0013-9580.2004.27904.x]

Other synonyms include delphinic acid, 3-methylbutyric acid, and isopentanoic acid.
