Isophthalaldehyde
Isophthalaldehyde is an organic compound with the formula C6H4(CHO)2. It is one of three isomers of benzene dicarbaldehyde, a reduced analog of phthalic acid. It is a colorless solid, although commercial samples often appear yellowish. One preparation entails the Sommelet reaction of α,α'-diamino-ortho-xylene. Reactions and use
Like many benzaldehydes, isophthalaldehyde forms a variety of Schiff base derivatives. Being bifunctional (having two formyl groups), isophthalaldehyde allows the formation of polymers or covalent organic frameworks upon reaction with di- or triamines. They also find use in metal coordination complexes. Related compounds
