 Disperse Blue 1 (CAS NO.2475-45-8) is also named as 1,4,5,8-Tetraamino-9,10-anthracenedione ; 1,4,5,8-Tetraaminoanthraquinone ; 1,4,5,8-Tetraminoanthraquinone ; 4-14-00-00487 (Beilstein Handbook Reference) ; 9,10-Anthracenedione, 1,4,5,8-tetraamino- ; Acetate Blue 6 ; Acetate Blue G ; Acetoquinone Blue L ; Acetoquinone Blue R ; Acetylon Fast Blue G ; C.I. 64500 ; C.I. Disperse Blue 1 ; C.I. Solvent Blue 18 ; CI Solvent Blue 18 ; Celanthrene Pure Blue BRS ; Celliton Blue BB-CF ; Celliton Blue Extra ; Celliton Blue G ; Fenacet Blue G ; Grasol Blue 2GS ; Serinyl Blue 3G ; Serinyl Blue 3GN ; Setacyl Blue 2GS ; Supracet Deep Blue R . Disperse Blue 1 (CAS NO.2475-45-8) is blue-black crystalline powder. It is insoluble in water. Disperse Blue 1 is an amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. When heated to decomposition Disperse Blue 1 emits toxic fumes of nitrogen oxides. Flash point data for Disperse Blue 1 are not available; however, it is probably combustible.
