2-Aminobenzaldehyde is an organic compound with the formula C6H4(NH2)CHO. It is one of three isomers of aminobenzaldehyde. It is a low-melting yellow solid that is soluble in water.[1]
Preparation and reactions
It is usually prepared by reduction of 2-nitrobenzaldehyde with iron[2] or iron(II) sulfate.[3] Like related aminoaldehydes, it is unstable with respect to self-condensation.
2-Aminobenzaldehyde is used to prepare quinolines by the Friedländer synthesis:
By template reactions, it also forms trimeric and tetrameric condensation products that have been studied as ligands.
