4-Methylbenzaldehyde is a simple aromatic aldehyde. It is commercially available, but may be prepared from the Friedel-Crafts formylation of toluene with carbon monoxide and hydrogen chloride under Gattermann-Koch conditions:.[1] 4-Methylbenzaldehyde has a cherry-like scent similar to benzaldehyde.
