TCI C0738 5-Chlorosalicylaldehyde (CAS 635-93-8) is a chlorinated salicylaldehyde bearing adjacent aldehyde and phenolic hydroxyl groups. This arrangement makes it a standard precursor for Schiff bases and for salen- and salophen-type tetradentate ligands used in coordination chemistry and catalysis. The 2-hydroxybenzaldehyde core also supports the synthesis of coumarins, benzofurans, and Schiff-base fluorescent probes. AMI Scientific supplies 5 g and 25 g packs; weigh the crystalline solid in a fume hood with protective equipment and store it tightly closed, cool, dry, and protected from light.
