Application

Salicyladehyde (2-Hydroxybenzaldehyde) may be used in the preparation of pyrocatechol via Dakin reaction.
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.
