Product Name:2-Naphthylamine-4,8-disulfonic acid
English Name:2-Naphthylamine-4,8-disulfonic acid
CAS No.:131-27-1
Aliases:2-Aminonaphthalene-4,8-disulfonic acid, Gamma-acid, Amino C acid
Molecular Formula:C10H9NO6S2
Physical Properties:White to grey crystalline powder or solid. Readily soluble in water, forming an acidic aqueous solution; slightly soluble in ethanol, insoluble in organic solvents such as ether and benzene. Usually exists in the form of sodium salt (e.g., disodium salt), with a high melting point and decomposes upon heating.
Uses:Used as a dye intermediate, mainly for the synthesis of azo dyes, reactive dyes, and acid dyes. Also applied in organic synthesis and as an analytical reagent. In research experiments, it serves as a fine chemical raw material.
