2-氨基苯并噻唑分子式：C7H6N2S分子量：150.20CAS号：136-95-8性质：叶状体结晶。熔点132℃，易溶于乙醇、乙醚和氯仿，溶于浓盐酸，极难溶于水。蒸馏时不分解。制备方法：由苯基硫脲与氯化硫反应得到。先将无水氯仿吸入搪玻璃锅中，于搅拌下加入苯基硫脲，慢慢升温到60-63℃，蒸出含水氯仿，冷却至40℃加入氯化硫，气相温度不高于40℃，以免物料结块。加完后4h逐步升温至61℃，在61-64℃回流反应10h。然后将其排到盛有一定水量和活性炭的蒸馏锅中，用直接蒸汽蒸馏回收氯仿到液相温度为98℃，并维持15min。回收完毕，加水稀释，加冰冷却，加液碱中和至pH值为4.1，再加活性炭后搅拌。冷却、抽滤，滤液用30%液碱中和至pH值为7.0-7.6，然后冷却到35-40℃，压滤、烘干（温度不超过80℃）即得成品。熔点128-130℃，收率74.4%。用途：染料中间体。用于生产阳离子紫3RL，还用合成3-甲基苯并噻唑腙用于生产阳离子紫2RL等，也是其他有机合成的原料。
