Chemical Information
FooDB Name4-Methylpentanal
Description4-Methylpentanal, also known as isohexanal or isocaproaldehyde, belongs to the class of organic compounds known as alpha-hydrogen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. 4-Methylpentanal is an extremely weak basic (essentially neutral) compound (based on its pKa). 4-Methylpentanal has been detected, but not quantified in, milk (cow). This could make 4-methylpentanal a potential biomarker for the consumption of these foods.
