2,6-Naphthalenedicarboxylic acid is an

organic compound In chemistry, organic compounds are generally any chemical compounds that contain carbon- hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. Th ...

with the formula C₁₀H₆(CO₂H)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. Pro ...

(PEN, poly(ethylene-2,6-naphthalene dicarboxylate)). It is also used in the synthesis of some metal-organic frameworks.

Preparation

The conjugate base of 2,6-naphthalenedicarboxylic acid, when heated, isomerizes to the 1,6-isomer, which is readily converted to 1,6-naphthalenedicarboxylic acid. It is also produced by oxidation of

2,6-diisopropylnaphthalene 2,6-Diisopropylnaphthalene (2,6-DIPN) is an organic compound with the formula C10H6(i-Pr)2 (where i-Pr = isopropyl). 2,6-DIPN is one of several isomers of diisopropylnaphthalene. It is a white or colorless solid.. 2,6-DIPN is plant growth regulat ...
