C.I. Direct Brown (CAS NO.16071-86-6) is also named as Aizen Primula Brown BRLH ; Aizen Primula Brown PLH ; Amanil Fast Brown BRL ; Amanil Supra Brown LBL ; Atlantic Fast Brown BRL ; Brown 4EMBL ; C.I. 30145 ; C.I. Direct Brown 95 ; CCRIS 168 ; CI 30145 ; Calcodur Brown BRL ; Chloramine Fast Brown BRL ; Cuprate(2-),(5-((4'-((2,6-dihydroxy-3-((2-hydroxy-5-sulfophenyl)azo)phenyl)azo)(1,1'-biphenyl)-4-yl)azo)-2-hydroxybenzoato(4-)), disodium ; Cuprofix Brown GL ; Direct Brown BRL ; Direct Fast Brown BRL ; Fastusol Brown LBRSA ; Fastusol Brown LBRSN ; Fenaluz Brown BRL ; Pontamine Fast Brown BRL ; Pontamine Fast Brown NP ; Pyrazol Fast Brown BRL ; Sumilight Supra Brown BRS ; Suprazo Brown BRL ; Suprexcel Brown BRL ; Tertrodirect Fast Brown BR ; Tetramine Fast Brown BRDN Extra ; Tetramine Fast Brown BRP . C.I. Direct Brown (CAS NO.16071-86-6) is a dark brown microcrystals or charcoal black powder. It is slightly water soluble. It is an azo compound. Azo dyes can be explosive when suspended in air at specific concentrations. . Toxic gases are formed by mixing azo compounds 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. However, it is probably combustible. |
