Descrizione generale

6-Hydroxy-2-naphthoic acid is a hydroxynaphthoic acid derivative. Whole cells of the recombinant Escherichia coli strain expressing CYP199A2 were reported to catalyze the regioselective oxidation of 6-hydroxy-2-naphthoic acid to afford 6,7-dihydroxynaphthoic acid. It can form co-crystals with caffeine.

Applicazioni

6-Hydroxy-2-naphthoic acid may be used in the synthesis of 5-bromo-6-hydroxy-2-naphthoic acid and liquid-crystalline epoxy resins.

A group of caffeine-containing co-crystals of hydroxy-2-naphthoic acids were synthesized and analyzed via single-crystal X-ray diffraction and IR analysis. The imidazole-carboxylic acid synthon was observed in co-crystals involving 1-hydroxy-2-naphthoic and 3-hydroxy-2-naphthoic acid. In the case of 6-hydroxy-2-naphthoic acid, the co-crystal
