| 外観 | 紫色～濃い紫色～暗い赤色粉末～結晶 | | 化学的特性 | ?1-Aminonaphthalene-5-sulfonic acid [84- 89-9]. (5-aminonaphthalene-1-sulfonic acid), Laurent’s acid, L acid, Purpurin acid, C10H9NO3S, Mr 223.24, crystallizes from hot water as needles of the monohydrate. The alkalimetal salts are all readily soluble in water. Bromination yields the 2,4-dibromo derivative, vigorous nitration gives 2,4-dinitro-1- hydroxynaphthalene, and sulfonation results in 1-aminonaphthalene-2,5,7-trisulfonic acid. 1- Hydroxynaphthalene-5-sulfonic acid is obtained by heating 104 with aqueous bisulfite (reverseBucherer reaction) or via the diazo compound. Caustic fusion produces 5-amino-1-hydroxynaphthalene. Coupling with diazo compounds takes place in the 2-position. | | 使用 | 5-Aminonaphthalene-1-sulfonic acid is an deriva- tizing agents in the precolumn derivatization of some chiral phenoxy acid. Cu(II) based on a dansyl derivative was synthesized with 29.2% overall yield by a seven-step synthetic procedure from the readily available starting material 5-aminonaphthalene-1-sulfonic acid. | | 使用 | Intermediate of dyestuff | | 定義 | ChEBI: 5-Amino-1-naphthalenesulfonic acid is a naphthalenesulfonic acid. | | 調製方法 | Laurent’s acid is coproduced with Peri acid as the minor component of a 5:2 isolated product ratio. | | 純化方法 | Crystallise the acid under nitrogen from boiling water and dry it in a steam oven [Bryson Trans Faraday Soc 47 522, 527 1951].
