Application

Salicylaldehyde may be used as starting reagent in the synthesis of novel unsymmetrical chiral Salen Schiff base ligands. It may be used in the preparation of salicylaldehyde phenylhydrazine, a useful indicator for the titration of organometallic reagents.
Salicyladehyde (2-Hydroxybenzaldehyde) may be used in the preparation of pyrocatechol via Dakin reaction.
