Specification
Disodium3-[(2,4-dimethyl-6-sulfonatophenyl)hydrazinylidene]-4-oxonaphthalene-1-sulfonatewith CAS number of 4548-53-2 is also known as Ponceau SX ; 12101Red ; 1306Red ; 2-(6-Sulfo-2,4-xylylazo)-1-naphthol-4-sulfonicacid,disodiumsalt ; 2-(6-sulpho-2,4-xylylazo)-1-naphthol-4-sulphonicacid,disodiumsalt ; 3-((2,4-dimethyl-5-sulfophenyl)azo)-4-hydroxy-1-naphthalenesulfonicacid,dis ; 3-((2,4-dimethyl-5-sulphophenyl)azo)-4-hydroxy-1-naphthalenesulphonicacid,d ; 3-[(2,4-dimethyl-5-sulfophenyl)azo]-4-hydroxy-1-naphthalenesulfonicacidis . Ponceau SX is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals.
