pale brown powder
Verwenden
6-hydroxy-2-naphthoic acid is used for preparation engineering plastics, organic pigments, liquid crystal materials, medicine, particularly as a monomer of heat-resistant material.
Allgemeine Beschreibung
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.
Synthese
6-Hydroxy-2-naphthoic acid [16712-64-4], mp 245 – 248℃, is synthesized by carboxylation of the potassium salt of 2-naphthol at 170 – 230℃. It couples with diazo compounds in the 5-position and undergoes sulfonation in the 4- and 7-positions.
