2-Formylbenzonitrile (CAS 7468-67-9) from TCI is the ortho isomer in which the aldehyde and nitrile groups sit adjacent on the aromatic ring. This proximity enables intramolecular cyclization pathways that are difficult to achieve with the meta or para isomers, giving access to isoindolinone, isoquinoline, and phthalazine frameworks. The aldehyde remains available for conventional Schiff base formation, reduction, and olefination, so a single reagent can serve both linear and annulation routes. AMI Scientific supplies this building block in 5 g and 25 g packs for laboratory-scale research.
