Isovaleric acid occurs naturally in many foods, such as cheese, soy milk, and apple juice. It is also a minor constituent of the perennial flowering plant valerian (Valeriana officinalis) |
|
Commercially, it is produced by the hydroformylation of isobutylene with syngas, forming isovaleraldehyde, which is oxidised to the final product |
