Phenylhydrazines are compounds containing a phenylhydrazide moiety, which consists of a hydrazide substituent attached to a phenyl group. Salicyaldehyde is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Salicyaldehyde can be found in chinese cinnamon, which makes salicyaldehyde a potential biomarker for the consumption of this food product.
