2,6-Naphthalenedicarboxylic acid is an
organic compound
Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-co ...

2. This colorless solid is one of several isomers of naphthalenedicarboxylic acid. It is a precursor to the high performance polyester
polyethylene naphthalate
Polyethylene naphthalate (poly(ethylene 2,6-naphthalate) or PEN) is a polyester derived from naphthalene-2,6-dicarboxylic acid and ethylene glycol. As such it is related to poly(ethylene terephthalate), but with superior barrier properties.

(PEN, poly(ethylene-2,6-naphthalene dicarboxylate)). It is also used in the synthesis of some
metal-organic frameworks.
Preparation
It was first prepared by Robert Evert and in 1876 by hydrolysis of 2,6-dicyanonaphthalene.
can be isomerized to 2,6-naphthalenedicarboxylic acid via the intermediacy of the dipotassium dicarboxylates.
It is also produced by oxidation of
2,6-diisopropylnaphthalene.
