Diformylcresol is an organic compound with the formula CH3C6H2(CHO)2OH.

The 2,6-diformyl derivative of p-cresol is the most common isomer and is a white solid at room temperature.

Diformylcresol condenses with amines to give diimines that are widely studied as binucleating ligands.

[2][3] Formyl groups (aldehydes) are fairly strong deactivating groups for electrophilic aromatic substitution reactions, hence double-addition to a phenol requires forcing conditions.

[4] The corresponding reaction of phenol would be expected to lead to formylation of the 4-position vs 2,6-selectivity.
