The IUPAC name of 2-Chlorophenothiazine is 2-chloro-10H-phenothiazine. With the CAS registry number 92-39-7, it is also named as 10H-Phenothiazine, 2-chloro-. The product category is Sulphur Derivatives. It is greyish to slightly green or brownish powder which should be obtained by the cyclization of m-dichloroaniline. What's more, it is highly toxic and flammable. It will produce toxic chloride, sulfur oxide and nitrogen oxide gas when buring. So the storage environment should be well- ventilated, low-temperature and dry. Keep 2-Chlorophenothiazine separate from raw materials of food.
