2-Chlorothioxanthone Use and Manufacturing
It is obtained by diazotization, condensation and ring closure of anthranilic acid. Firstly, anthranilic acid, hydrochloric acid, and sodium nitrite are mixed, and the diazotization reaction is carried out at 0-5°C to obtain the diazonium salt solution; then the condensation reaction is carried out with the alkali solution of p-chlorothiophenol, and the product is acidified with hydrochloric acid. 4-Chlorodiphenylsulfur-2'carboxylic acid is catalyzed and ring closed with concentrated sulfuric acid at 60-70°C to obtain the finished product.
Used as the intermediate of the drug chloroprothix
