Application

2,5-Dimethoxybenzene-1,4-dicarboxaldehyde can be used as a reactant to synthesize:
  • Polymeric Schiff bases using aliphatic or aromatic diamines via polycondensation reaction[1].
  • 1,4-Bis-(α-cyano-4-methoxystyryl)-2,5-dimethoxybenzene using (4-methoxyphenyl)acetonitrile via Knoevenagel reaction in the presence of potassium t-butoxide and tetrabutylammonium hydroxide[2].
