| Hazard Information | Back Directory | [Chemical Properties]
7-Acetamido-4-hydroxynaphthalene-2-sulfonic acid [6334-97-0] N-acetyl J acid, is produced by reaction of the sodium salt of J acid with acetic anhydride in aqueous solution at 20 – 30℃, followed by heating at 95℃ with sodium carbonate to hydrolyze any O-acetyl derivative present (yield 85 %). It is used to produce C.I. Acid Orange 27, C.I. Acid Red 137, and C.I. Direct Red 77. | [Uses]
7-(Acetylamino)-4-hydroxy-2-naphthalenesulfonic acid is used as an intermediate for reactive dyes, such as Reactive Orange 72. | [Flammability and Explosibility]
