Ditolylbis(azonaphthionic acid) (CAS NO.992-59-6) is also called 1-Naphthalenesulfonic acid, 3,3'-((3,3'-dimethyl(1,1'-diphenyl)-4,4'-diyl)bis(azo))bis(4-amino-, disodium salt ; AI3-62957 ; Amanil purpurine ; Amanil purpurine 4B ; Benzanil purpurine 4B ; Benzopurpurine 4BKX ; C.I. Direct Red 2 disodium salt ; Cerven prima 2 [Czech] ; Chrome Leather Red 4B ; Diaphtamine Purpurine 4B ; Diaphtamine purpurine ; Disodium o-tolidinediazobis(1-naphthylamine-4-sulfonate) ; Eclipse Red ; Erie Benzo 4BP ; Mitsui benzopurpurine 4BX ; NSC 5015 ; Phenamine purpurine 4B ; Purpurin 4B ; Tetrodirect Red 4B . Ditolylbis(azonaphthionic acid) (CAS NO.992-59-6) is dark red or brown powder. It is stable and incompatible with strong oxidizing agents. Ditolylbis(azonaphthionic acid) is also insoluble in water. Ditolylbis(azonaphthionic acid) 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. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. Flash point data for Ditolylbis(azonaphthionic acid) are not available. Ditolylbis(azonaphthionic acid) is probably combustible. |
