2-AMINO-5,6-DIMETHYLBENZOTHIAZOLE Usage And Synthesis
Chemical Properties    white to yellow or beige crystalline powder
General Description    Off-white crystalline solid.
Air & Water Reactions    Insoluble in water.
Reactivity Profile    An amine, organosulfide. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. 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.
Health Hazard    ACUTE/CHRONIC HAZARDS: When heated to decomposition, 2-AMINO-5,6-DIMETHYLBENZOTHIAZOLE may emit toxic fumes of NOx and SOx.
Fire Hazard    Flash point data for 2-AMINO-5,6-DIMETHYLBENZOTHIAZOLE are not available. 2-AMINO-5,6-DIMETHYLBENZOTHIAZOLE is probably combustible.
