| | 1,6-Dihydroxynaphthalene Usage And Synthesis |
| Chemical Properties | Beige powder | | Uses | 1,6-Dihydroxynaphthalene is used as a dye and pharmaceutical intermediate. | | Definition | ChEBI: Naphthalene-1,6-diol is a naphthalenediol. | | Synthesis | 1,6-Naphthalenediol [575-44-0], mp 138℃, is synthesized by caustic fusion of naphthalene1,6-disulfonic acid at 330 C. It couples with diazotized anilines to form disazo and trisazo derivatives. | | Purification Methods | Crystallise it from *benzene or *benzene/EtOH after treatment with charcoal.
