Light yellow to grey needle crystal | [Uses]
2,7-Dihydroxynaphthalene can be used as starting material for the synthesis of sulfonic acids and divinylnaphthalenes.
| [Uses]
2,7-Dihydroxynaphthalene is a reagent used in the preparation of monomers of high carbon materials. Also used in the synthesis of splitomicin analogues.
| [Synthesis]
2,7-Naphthalenediol [582-17-2], mp 194℃, is produced by caustic fusion of naphthalene-2,7- disulfonic acid or 2-hydroxynaphthalene-7-sulfonic acid at 300℃. It undergoes amination at 250℃ to give 2,7-naphthalenediamine and couples with diazotized anilines in the 1-position or in the 1,8-positions. It forms a resin with formaldehyde. |
