Description

Application

Salicylaldehyde can be used to synthesize:

Salicylidene-tris(aminomethyl)ethane chelating agent which can form metal chelates with Fe³⁺, probes for ¹⁹F magnetic resonance imaging.
Schiff base ligands via condensation with cycloalkylamines.
3-acetylcoumarin, an intermediate for the synthesis of various pyrrolidone fused coumarins and furan fused coumarins.
Biologically important 2-amino-4H-chromene scaffolds via multicomponent reaction with nitroalkanes and malononitrile.
