描述
Trans-octen-2-al, also known as (E)-2-octenal or 2-octenal, (E)-isomer, is a member of the class of compounds known as medium-chain aldehydes. Medium-chain aldehydes are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, trans-octen-2-al is considered to be a fatty aldehyde lipid molecule. Trans-octen-2-al is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Trans-octen-2-al can be found in ginger and potato, which makes trans-octen-2-al a potential biomarker for the consumption of these food products.
