用途有機合成原料。
説明2-Aminonaphthalene-6-sulfonic acid [93- 00-5]. (6-aminonaphthalene-2-sulfonic acid), Bronner acid, C10H9NO3S, Mr 223.24, crystallizes from water as the monohydrate in plates although only 0.2 % soluble at 100℃. Sulfonation with 20 % oleum at 20℃ gives a mixture of 1,6- and 6,8-disulfonic acids.
純化方法Crystallise the acid from a large volume of hot water. The diethylamine salt has m 190.5-192o (from EtOH/isoBuOH), and the S-benzylisothiuronium salt has m 330o (from nBuOH). [Beilstein 14 H 760, 14 II 463, 14 III 2249, 14 IV 2804.]
