2,3-Dihydroxynaphthalene Usage And Synthesis
Chemical PropertiesOff white to redish white powder. 2,3-Naphthalenediol [92-44-4], mp 161℃, gives a dark blue color with iron(III) chloride; is aminated to 2- amino-3-naphthol at 140℃ and 2,3-naphthalenediamine at 240℃; and couples with diazotized anilines in the 1- or 1,4-positions.
Uses2,3-Naphthalenediol is used in cosmetics asa component of oxidative hair dye. It is usedat a concentration of <0.1%.
Uses2,3-Dihydroxynaphthalene is used in making dyes, pigments, fluorescent whiteners, tanning agents, antioxidants, and antiseptics.
Uses2,3-Dihydroxynaphthalene may be used in the following studies:
  • Construction of dinaphtho[2,1-b;2′,3′-d]furan-6-ol, via dehydration reaction in the presence of strong acid.

  • As fused ring catecholate type ligand for the surface modification of nanocrystalline TiO2 particles.

  • As adsorptive and competing ligand during the chemical speciation of iron in seawater by cathodic stripping voltammetry.

  • Synthesis of cyclotriphosphazene derivatives, used as non-halogen flame retardants
