Description and Uses
3-ethoxysalicylaldehyde is also known as o-ethyl vanillin. 3-ethoxysalicylaldehyde often appears as a by-product in the production process of ethyl vanillin, which gradually becomes an alternative to vanillin since it possesses a flavor and odor approximately 3 ～ 4 times as intense as vanillin. In recent years, it has been discovered that 3-ethoxysalicylaldehyde possesses potential applications in optical utilization, biology, catalysis, and corrosion inhibition. Moreover, 3-ethoxysalicyaldehyde has been applied in various medicinal applications[1].
3-Ethoxysalicylaldehyde was used in the preparation of:
- Schiff base ligand via condensation with trans-1,2-diaminocyclohexane
- substituted salen-type Schiff base ligands
- a new Schiff base, 2-ethoxy-6-[(3-methylaminopropylimino)methyl]phenol, via reaction with N-methylpropane-1,3-diamine
