Verwenden
4-Methylvaleric acid has been used in asymmetric synthesis of (4S)-4-isopropyl-3-[(2S)-2,4-dimethyl-valeryl)]-2-oxazolidinone. It is a versatile building block used in the synthesis of various pharmaceutical and biologically active compounds, including inhibitors and antagonists. It is involved in the synthesis of novel series of high affinity, functionally potent antagonists of the CCR1 receptor.
Application
4-Methylvaleric acid, although identified in Nature, has found very little, if any, use in perfumes or flavors. It is mentioned mainly for the sake of completing the monographs on Methylpentanoic acids.
Definition
ChEBI: A methyl-branched fatty acid that is pentanoic acid with a methyl group substituent at position 4. It is a metabolite of 20 alpha-hydroxycholesterol
Allgemeine Beschreibung
Conductimetric detection of 4-methylvaleric acid on unfunctionized polymethacrylate resin (TSKgel G3000PWXL) columns has been reported.
