| | 2-Amino-4-methylbenzothiazole Usage And Synthesis |
| Chemical Properties | OFF-WHITE TO SLIGHTLY BEIGE CRYSTALLINE POWDER | | Uses | 2-Amino-4-methylbenzothiazole was used in the synthesis of N-(4-methyl-1,3-benzothiazol-yl)-N-[(1,4,5,8-tetramethoxy-2-napthyl)methylidene]amine and Schiff′s base via condensation with 2-acetonaphthone. | | General Description | White powder. | | Air & Water Reactions | 2-Amino-4-methylbenzothiazole is sensitive to moisture. 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-4-methylbenzothiazole emits very toxic fumes of SOx and NOx. | | Fire Hazard | Flash point data for 2-Amino-4-methylbenzothiazole are not available. 2-Amino-4-methylbenzothiazole is probably combustible. |
