Sinapaldehyde is an organic compound that is an intermediate in the formation of lignin.^[3]

In Arabidopsis thaliana, this compound is part of the lignin biosynthesis pathway. The enzyme dihydroflavonol 4-reductase uses sinapaldehyde and NADPH to produce sinapyl alcohol and NADP⁺.^[4]

It is found in Senra incana (Hibisceae). It is a low molecular weight phenol that is susceptible to be extracted from cork stoppers into wine.^[5]
