4-FORMYL-3-HYDROXYBENZOIC ACID Usage And Synthesis

Uses

4-Formyl-3-hydroxybenzoic acid can be used as a reactant to prepare:

• A pH-sensitive fluorescent probe 4,4′-(hydrazine-1,2-diylidene bis(methanylylidene)) bis(3-hydroxybenzoic acid (HDBB) by one-step condensation reaction with hydrazine.
• 2-Oxo-2H-1-benzopyran-3,7-dicarboxylic acid by condensation reaction with diethyl malonate.
• Schiff base ligands for the preparation of stable and functional Schiff base metal complexes.
