5-(tert-Butyl)-2-hydroxybenzaldehyde (TCI B6598, CAS 2725-53-3) is a salicylaldehyde derivative bearing a bulky tert-butyl substituent at the 5-position. The adjacent hydroxyl and aldehyde groups make it a classic precursor for Schiff base formation with primary amines. Condensation with diamines gives salen- and salophen-type ligands that are widely used to prepare transition metal complexes for catalysis research. The scaffold is also popular in the design of fluorescent chemosensors, and the 5 g and 25 g packs cover both exploratory and routine ligand synthesis.
