Medium-chain aldehydes are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Nona-trans-2-cis-6-dien-1-al is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Nona-trans-2-cis-6-dien-1-al can be found in common wheat, cucumber, tea, and watermelon, which makes nona-trans-2-cis-6-dien-1-al a potential biomarker for the consumption of these food products.
