Structure
Identity
Also known as: Pentanoic acid, 2-methyl-, Valeric acid, 2-methyl-, Valeric acid, α-methyl-, 2-Methylpentanoic acid, Methylpropylacetic acid, α-Methylvaleric acid, 2-Pentanecarboxylic acid, 2-Methyl-n-valeric acid, DL-2-Methylpentanoic acid, (±)-2-Methylpentanoic acid, NSC 8406, 2-methylpentanoic acid.
Can 2-Methylvaleric acid be labeled natural?
Since 2-Methylvaleric acid is found in nature, US labeling follows how it was obtained: natural flavor from a natural source and a natural process, artificial when 2-Methylvaleric acid is synthesized. In the EU and UK the natural claim likewise needs the natural route, while Mercosur and Mexico keep a third class, identical-to-natural, for the synthetic material.
- United States
- Natural or artificial, by process
- European Union and UK
- Natural only from natural material
- Mercosur and Mexico
- Natural or identical-to-natural
How each market defines the classes: natural vs artificial flavor under 21 CFR 101.22.
