Medium-chain aldehydes are an aldehyde with a chain length containing between 6 and 12 carbon atoms. 2,4-undecadienal is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2,4-undecadienal is a caramellic and spicy tasting compound found in nuts, which makes 2,4-undecadienal a potential biomarker for the consumption of this food product.
