Coniferyl aldehyde DMACA reagent 2-Nitrocinnamaldehyde Sinapaldehyde is an organic compound with the formula HO(CH3O)2C6H2CH=CHCHO.

It is an intermediate in the formation of sinapyl alcohol, a lignol that is a major precursor to lignin.

[5] Sinapaldehyde is reduced to the alcohol by the action of dehydrogenase enzymes.

[4] In Arabidopsis thaliana, the enzyme dihydroflavonol 4-reductase uses NADP+ to reduce sinapaldehyde to sinapyl alcohol.

It is a low molecular weight phenol that is susceptible to extraction from cork stoppers into wine.
